In order for a moving bowling ball and a moving Ping-Pong ball to have the same momentum what must happen to the speed of both-balls?
Right. p = mv. Therefore if p is to remain constant, if we increase m by some factor, then we must decrease v by exactly the same factor. So, if the bowling ball has, say, 256 times the mass of the ping pong ball, the ppb must be moving at a velocity 256 times faster in order to have the same momentum as the bb.
It's also important to remember the difference between kinetic energy and momentum in these problems.
Way to do it for her (him?), CANGAS. Homework problems (or anything that looks like one) shouldn't be just answered like that. Educatoin is about encouraging independent thought, y'know?

EducatOIn is about helping someone to understand something that they do not previously understand. My elementary education would have had much fewer snags if a few so-called teachers had been aware of helping us rather than only saying a fact and turning away. There is no better teaching tool than giving a learner a worked out example so that they have every opportunity to understand what is supposed to be going on. It is a pity that seemingly so few of your own teachers knew that. Right?
No, a better teaching tool is to allow the learner to discover their own approach. The constructivist approach to education is something good educators love.
I have very strong feelings about having a positive and helpful approach to education of any learner. Enough of this off-topic jibber jabber in this thread. I might be willing to discuss education priorities in the proper venue. If you start a thread on the subject and I find it then maybe I can somehow come up with useful comments.
