If all of the kinetic energy is conserved, the collision is completely elastic
3) The system is composed of two pool balls. The white cue
ball has a mass of 0.17 kilograms while the 8 ball has a
mass of 0.15 kilograms. The cue ball is traveling initially
at 5 meters per second. It collides with the 8 ball and
comes to a complete stop. Calculate the velocity of the 8
ball after the collision.

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)?
