# 1) Explain the difference between Kinetic and Potential Energy # 2 @ Derive the Work/ Energy Theorem which says W= KAK: ( b) A 10 kq block is pushed with a force of 20 NY Assuming the initial velocity is 3 m/s , what's the final velocity of the block after 1 meters . # 3 ) How high does a ball go if a 25 meter person throws it up in the air at 16 mis # 4) A spring with spring constant 200 NM is compressed by a 5ng block by 0.6 met. After letting go of the block, what is the final velocity ? Assume the initial velocity is zero
