You wish to push a cart across a friction less surface, so you apply a 20 N force for a period of 3 seconds. As a result, the
cart goes from rest to a velocity of 2.3 m/s. What is the mass of
the cart?

How much work would be needed to raise the payload from the surface of the moon (i. e., x = r) to an altitude of 5r miles above the surface of the moon (i. e., x = 6r)?

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
