Suppose the ring rotates once every 4.80 s . If a rider's mass is 57.0 kg , with how much force does the ring push on her at the top of the ride

Answer:

The work completed is 73.5 Joule

Explanation:

Mechanical Work

Mechanical work is the amount of energy transferred by a force that moves an object by a certain distance. It's a scalar quantity, with SI units of joules.

Being  the force and  the displacement the work is calculated as:

W=F.s

The box of m=5 kg is lifted by a distance of s=1.5 m. The force applied to lift the box is equal to the weight of the box, assuming it's lifted at a constant speed, thus:

F = mg = 5 * 9,8 = 49 N

The work is:

W = 49 N * 1.5 m

W = 73.5 J

The work completed is 73.5 Joule

Given function isv(t) = t³ +13t²+47t-35and time interval is 1≤t≤7. We have to calculate:

(a) Displacement

(b) Total Distance

(a) Displacement:

Displacement is defined as the shortest distance between initial and final points. We can find the displacement of a particle with the help of following formula:

Displacement = Final Position - Initial PositionHere, the particle moves along a straight line, and we don't know the initial and final position.  Thus, the displacement of the particle is 219 ft.(b) Total Distance:Total distance traveled by the particle is the sum of all the distances covered by it in different intervals.

Thus, we have two real roots of the given equation:t₁

≈ - 6.548t₂

≈ 0.215

Therefore, ∫|v(t)|dt = 309

As we have to find the total distance, we have to add both the cases. Therefore,

Total Distance =∫|v(t)|dt  [from 1 to 7]

=∫|v(t)|dt [from 1 to 7]

=∫|v(t)|dt (from 1 to 1.215) +|v(t)|dt (from 1.215 to 7) = 252 + 309= 561 ft Thus, the total distance traveled by the particle is 561 feet.

The event horizon of a black hole is the boundary beyond which nothing, not even light, can escape its gravitational pull. The size of the event horizon is directly related to the mass of the black hole.

Specifically, the Schwarzschild radius formula can be used to determine the size of the event horizon, which is given by Rs = 2GM/c^2, where Rs is the Schwarzschild radius (event horizon radius), G is the gravitational constant, M is the mass of the black hole, and c is the speed of light. For a 10Msun black hole, the event horizon will be larger than that of a 1Msun black hole. This is because the mass term (M) in the formula directly affects the event horizon size. When comparing a 10Msun black hole to a 1Msun black hole, the 10Msun black hole has 10 times the mass, which will result in a correspondingly larger event horizon. The escape velocity for both black holes is indeed the speed of light, but their event horizons will differ in size due to the variation in mass.

The astronaut's height, as measured from the space station, will appear contracted due to relativistic effects. Due to relativistic length contraction, the astronaut's height, as measured from the space station, appears to be approximately 3.52 meters.

According to the theory of special relativity, objects in motion relative to an observer will experience length contraction along the direction of motion. In this case, the spaceship is moving at a speed of 0.9 times the speed of light (0.9 c) relative to the space station.

The length contraction factor, denoted by γ, can be calculated using the Lorentz factor:

γ = 1 / √(1 - v²/c²)

Where v is the velocity of the spaceship and c is the speed of light. Plugging in the values, we have:

γ = 1 / √(1 - 0.9²)

γ ≈ 1.92

To determine the astronaut's height as measured from the space station, we multiply her actual height by the length contraction factor:

Height (as measured from the space station) = Actual height × γ

Height (as measured from the space station) = 1.83 m × 1.92

Height (as measured from the space station) ≈ 3.52 m

Therefore, due to relativistic length contraction, the astronaut's height, as measured from the space station, appears to be approximately 3.52 meters.

The board's displacement during the acceleration time after the sailboard was hit by the gust is 32.9 m.

The magnitude of the board's displacement can be calculated with the following equation:

\(x_{f} = x_{i} + v_{i}t + \frac{1}{2}at^{2}\)

Where:

\( x_{f} \): is the final displacement =?

\( x_{i} \): is the initial displacement = 0

\(v_{i}\): is the initial velocity  

t: is the time = 5.42 s

a: is the acceleration = 0.714 m/s²  

Since the hits the sailboard at 48.8° from the original direction, the initial velocity is:  

\(v_{i} = v*cos(\theta) = 6.28 m/s*cos(48.8) = 4.14 m/s\)

Hence, the displacement is:

\(x_{f} = v_{i}t + \frac{1}{2}at^{2} = 4.14 m/s*5.42 s + \frac{1}{2}0.714 m/s^{2}*(5.42 s)^{2} = 32.9 m\)

Therefore, the magnitude of the board's displacement is 32.9 m.

To determine the minimum speed that the motorcycle must have at the top of the loop to make it safely around, we need to consider the forces acting on the motorcycle at that point.

At the top of the loop, the motorcycle is experiencing two forces: the force of gravity pulling it downward and the normal force exerted by the track pushing it upward. The minimum speed required is when the normal force becomes zero, indicating that the motorcycle is just about to lose contact with the track.The net force acting on the motorcycle at the top of the loop is the centripetal force, which is given by:
F_net = m * (v^2 / r)
Where:F_net is the net force.m is the mass of the motorcycle (250 kg).v is the speed of the motorcycle.r is the radius of the circular track (12 m).At the top of the loop, the net force is the difference between the gravitational force and the normal force:
F_net = mg - N
Setting the net force equal to zero (N = 0), we can solve for the minimum speed:
mg = m * (v^2 / r)
Canceling out the mass:
g = v^2 / r
Solving for v:
v = √(g * r)
Plugging in the values:
v = √(9.8 m/s^2 * 12 m)
v ≈ √(117.6 m^2/s^2)
v ≈ 10.85 m/s
Therefore, the minimum speed that the motorcycle must have at the top of the loop to make it safely around is approximately 10.85 m/s.

The composition of a comet compared with that of the Sun is C "Comets are made of ice and dust, while the Sun is made of gas".

Comets are small, icy bodies that originate from the outer solar system and are composed mainly of frozen water, carbon dioxide, methane, and ammonia, along with dust and small rocky particles. When a comet approaches the Sun, its icy material vaporizes, creating a glowing coma (a hazy atmosphere around the nucleus) and a tail that points away from the Sun due to the solar wind.

On the other hand, the Sun is a giant ball of hot, glowing gas, composed mainly of hydrogen (about 73% of its mass) and helium (about 25% of its mass), with trace amounts of other elements like oxygen, carbon, and iron. The Sun generates energy through nuclear fusion reactions in its core, which convert hydrogen into helium and release a tremendous amount of energy in the process.

Therefore, the composition of a comet is quite different from that of the Sun. While both objects contain some water (in the form of ice for comets and vapor for the Sun), comets are predominantly made of ice and dust, while the Sun is predominantly made of gas, with only a small amount of solid material in its core.

Explanation:

The potential energy of an object at a height h above the earth’s surface is given by the formula U = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height above the earth’s surface.

Given that the object has a potential energy of 1200 J and a mass of 20 kg, we can rearrange the formula to find the height h:

h = U / (mg)

Substituting the given values, we get:

h = 1200 J / (20 kg x 9.81 m/s^2) = 6.12 m

Therefore, the object is at a height of 6.12 meters above the earth’s surface.

Given that mass is independent of everything, the first part of the question's response is straightforward: As mass does not change as you move from one location in the universe to another, the boy on the moon will still have the same mass as the boy on Earth.
