According to Newton's First Law of Motion, the answer is that it needs an external force and an internal force to stay in motion. While it is true that momentum can act as a force to change its behavior, this does not necessarily explain why the rock does not stay in motion at a constant velocity.

It involve understanding the various forces at play when an object is in motion. In this case, the rock is subject to both internal and external forces that affect its motion. Internal forces, such as friction between the molecules within the rock, can slow it down and eventually bring it to a stop. External forces, such as air resistance and gravity, can also impact its motion.

For example, if you throw the rock with enough force, it may initially maintain its velocity due to its momentum. However, as it travels through the air, air resistance will gradually slow it down until it eventually hits the ground. Similarly, the force of gravity will also affect the rock's motion, pulling it downward towards the earth's surface. As a result, the rock will not stay in motion at a constant velocity because it is subject to a variety of forces that can impact its movement.

In summary, the reason why a rock thrown does not stay in motion at a constant velocity is due to the presence of internal and external forces that act on it. While momentum can play a role in its behavior, it is not the sole factor that determines its motion

The expression for the buoyant force is F = ρghs²

Buoyant force is the force exerted on a object by a liquid.

Given that the pressure from the fluid at a certain depth is given by P = P₀ + ρgh where

We know that the buoyant for is due to the pressure difference frm the top and bottom of the fluid.

Since

P = P₀ + ρgh

P - P₀ = ρgh

ΔP =  ρgh

Now, we know that pressure difference, ΔP = F/A where

So, making F subject of the formula, we have that

F = ΔPA

Now since the object is a perfect cube of length, s, its area at its bottom surface perpendicular to F is A = s²

So, F = ΔPA

F = ΔPs²

So, substituting ΔP into the equation, we have that

F = ΔPs²

F = ρghs²

So, the buoyant force is F = ρghs²

The average force per unit area exerted on the passenger with no seatbelt 5,400,000 N/m²

The average force per unit area for the passenger with seat belt 18,750 N/m²

The known parameters are;

The velocity of the car, v₀ = 15 m/s

The time it takes the passenger not wearing seat belt to strike the windshield, \(t_{ns}\) = 0.03 s

Area of contact between the head and the windshield, \(A_{ns}\) = 5 × 10⁻⁴ m²

The mass of the head, \(m_{h}\) = 5.4 kg

Time taken for the passenger wearing seat belt to come to rest, \(t_s\) = 0.50 s

The mass of the passenger wearing seatbelt, \(m_s\) = 75 kg

Area of the seat belt in contact with the passenger, \(A_s\) = 0.12 m²

Required:

To find the average force per unit area exerted on the two passengers

Solution:

According to Newton's second law on motion, force is equal to the product of mass and acceleration

\(Acceleration, \overline a = \dfrac{Change \ in \ velocity}{Elapsed \ time} = \dfrac{v - v_0}{t}\)

Therefore, the acceleration, force and average force per unit area of the passenger with no seat belt;

\(Acceleration, \overline a_{ns} = \dfrac{0 - 15 \, m/s}{0.03 \, s} = 500 \, m/s^2\)

\(F_{ns}\) = \(m_{h}\) × \(\overline a_{ns}\)

Which gives;

\(F_{ns}\) = 5.4 kg × 500 m/s² = 2,700 N

Force per unit area = Force/Area

\(P_{ns} = \dfrac{2,700 \, N}{5 \times 10 ^{-4} \ m^2} = 5,400,000 \ N/m^2\)

The average force per unit area exerted on the passenger with no seatbelt, \(P_{ns}\) = 5,400,000 N/m²

\(Acceleration, \overline a_{s} = \dfrac{0 - 15 \, m/s}{0.5 \, s} = 30 \, m/s^2\)

\(F_{s}\) = \(m_{b}\) × \(\overline a_{s}\)

Which gives;

\(F_{s}\) = 75 kg × 30 m/s² = 2,250 N

Force per unit area = Force/Area

The average force per unit area, for the passenger with seat belt is therefore;

\(P_{s} = \dfrac{2,250\, N}{0.12 \ m^2} = 18, 750\ N/m^2\)

The average force per unit area for the passenger with seat belt, \(P_s\) = 18,750 N/m²

Answer:

v_squid = - 2,286 m / s

Explanation:

This exercise can be solved using conservation of the moment, the system is made up of the squid plus the water inside, therefore the force to expel the water is an internal force and the moment is conserved.

Initial moment. Before expelling the water

          p₀ = 0

the squid is at rest

Final moment. After expelling the water

         \(p_{f}\) = M V_squid + m v_water

         p₀ = p_{f}

          0 = M V_squid + m v_water

           c_squid = -m v_water / M

The mass of the squid without water is

            M = 9 -2 = 7 kg

let's calculate

           v_squid = 2 8/7

           v_squid = - 2,286 m / s

The negative sign indicates that the squid is moving in the opposite direction of the water

The period of the pendulum on the surface of Mars, where g = 3.71m/s², would be the same as the period on Earth, 1.70s.  The pendulum on the surface of Mars has a period of roughly 3.31 seconds, according to our calculation of this expression.

A basic pendulum's period is determined by the equation T = 2(L/g), where T is the period, L is the pendulum's length, and g is the acceleration brought on by gravity.

L = (T/(2))2g can be solved for on Earth with a period of 1.70s by rearranging the equation.

Using the same equation and the Mars surface gravity, g = 3.71m/s2, we can now get the period on Mars' surface: T\(_{mars}\) = 2(L/g\(_{mars}\)).

The equation T\(_{mars}\) = 2(((T/(2))2g)/(g\(_{mars}\))) is obtained by substituting the expression for L and the surface gravity of Mars.

T\(_{mars}\) = T(g/g_Mars), to simplify the formula.

T\(_{mars}\) = 1.70s(9.81m/s2 / 3.71m/s) is the result of plugging in the data. The pendulum on the surface of Mars has a period of roughly 3.31 seconds, according to our calculation of this expression.

The force is exerted by the elevator is (c) 1600N.

We are given that,

Weight = m = 800 Kg

Acceleration = a = 9.8 m/s²

Acceleration due to gravity = g = 9.8 m/s²

Force exerted by the elevator on the man = f = ?

f = mg + ma

Substituting the values we get,

f = m X (g + a)

f = 800 X (9.8 + 9.8)

f = 800 X 19.6

f = 15680 N

f ≈ 1600 N

The correct answer is ○ 8.91.

The critical angle for an air-glass interface is the angle of incidence at which the refracted ray is at 90 degrees to the surface, meaning the angle of refraction is 90 degrees.

However, if the angle of incidence is greater than the critical angle, then total internal reflection occurs and no refracted ray is formed.

In this scenario, the reflected ray is 100 percent polarized, which means that it vibrates in only one plane.

The angle of refraction can be determined using Snell's Law, which states that n1sinθ1 = n2sinθ2,

where n1 and n2 are the refractive indices of the media on either side of the interface and θ1 and θ2 are the angles of incidence and refraction, respectively.

Since the incident ray is in air and the interface is with glass, we can assume that n1 = 1 and n2 = 1.5. Using Snell's Law, we can find the angle of refraction to be closest to 8.91 degrees.

Therefore, the answer is ○ 8.91.

The distance travelled by the airplane before takeoff is 1721 m.

2. The acceleration of the race car is 11.2 m/s², and Distance travelled by the car is 79.9 m.

3. The acceleration of the bullet is 1.62 * 10⁵ m/s².

The distance travelled by the airplane before takeoff is determined using the formula:

s = ut + ¹/₂at²

u = 0; a = 3.20 m/s², t = 32.8 s

s = 0 * 32.0 +  ¹/₂ * 3.2 * 32.8²

s = 1721 m

2. The acceleration of the race car is calculated as follows:

a = (v - u)/t

v = 46.1 m/s, u = 18.5 m/s, t = 2.47 s

a = (46.1 - 18.5)/2.47

a = 11.2 m/s²

Distance travelled, s = 18.5 * 2.47 + ¹/₂ * 11.2 * 2.47²

s = 79.9 m

3. The acceleration of the bullet is calculated as follows:

a = (v² - u²)/2s

where v = 0 m/s, u = 521 m/s, s = 0.840 m

a = (0² - 521²)/2 * 0.840
