-So the trick here is reading. So, a ping pong ball and a bowling
ball are both rolling towards you. They have the same momentum. Since they both have the
same momentum, and the change in momentum with respect
to time is the force, if you have same
momentum, same force, it’s going to take the same
time to bring them to rest. Now, which one is moving faster? MULTIPLE STUDENTS: The ping pong ball. Yeah, because it has much less mass.
