A net force of 200 N acts on a 100-kg rock, and a force of the same magnitude acts on a 130-g stone. How does the
rate of change of the rock’s velocity compare to the rate of change of the stone’s velocity? Justify your answer
mathematically.
A bowling ball and a ping-pong ball are rolling toward you with the same momentum. Use mathematical analysis to
answer the following: If you exert the same force to stop each one, which takes a longer time to bring to rest?
