Greg and Karissa are about to start racing on their skateboards. Greg pushes off of the ground with 40 newtons of force. Karissa pushes off of the ground with 80 newtons of force. Greg and Karissa have the same mass.
How will Greg's acceleration compare with Karissa's acceleration?
Answers
Answer:
Greg's acceleration will decreace faster than Karissa will.
Explanation:
If Greg pushed off with less force and Karissa pushes off with more and they weigh the same Greg slows down before Karissa does. I hope this helped. :)
Karissa's acceleration is is greater than Greg's acceleration.
What is force?The definition of force in physics is: The push or pull on a massed object changes its velocity. An external force is an agent that has the power to alter the resting or moving condition of a body. It has a direction and a magnitude.
A spring balance can be used to calculate the Force. The Newton is the SI unit of force.
Let the mass of Greg and Karissa is m.
Force applied by Greg = 40 Newton.
Force applied by Karissa = 80 Newton.
From Newton's second law of motion, we know that:
Force = mass × acceleration
Acceleration = force/mass
Hence, Greg's acceleration is = 40/m m/s²
Karissa's acceleration is = 80/m m/s²
As 80 > 40; 80/m > 40/m
So, Karissa's acceleration is is greater than Greg's acceleration.

O A. 408 J
O B. 7,840,000 J
O C. 2J
O D. 39,200 J
Answers
Answer:
39,200J
Explanation:
just took the test
The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J
What is potential energy ?Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.
mass(m) = 10kg
g (acceleration due to gravity) = 9.8m/s^2
altitude(height (h)) = 400m
Meteor's Potential energy = m * g * h
= 10 * 9.8 * 400 = 39200 J
correct option will be a) 39200 J

See how a block and tackle system can increase your mechanical advantage. You will need two broomsticks, a rope, and two helpers.
A. Give each helper a broom stick and have them stand facing each other holding the broomstick firmly in both hands in a horizontal position. The broomsticks should be at the same level, about two feet apart.
B. Tie one end of the rope to one of the broomsticks. (You may need to have one of your helpers hold the knot firmly in one hand as he or she holds the broomstick to help anchor it.)
C. Wrap the rope around the other broomstick, as in a simple pulley system, and pull on the free end of the rope. Your helpers should resist your pulling. What happens? Can you pull the broomsticks together?
D. Now weave the rope back over the first broomstick, so you have a double pulley. Pull on the free end. What happens now? Can you pull the broomsticks together? What is your mechanical advantage?
E. Try weaving the rope over the broomsticks one or two more times. Describe what happens, and state the mechanical advantage of each situation.
F. Write a summary of what happened and an explanation using the terms: force distance work mechanical advantage
