In order for a moving bowling ball and a moving Ping-Pong ball to have the same momen

Recommended Posts

Well that depends on how fast they are moving to begin with.



That peice of information, plus this equation is all you'll need. (plus the assumption that a bowling ball is far more massive then a pingpong ball.)


momentum = velocity x mass.

Obviously, the bowling ball will have a larger mass than the ping pong ball. Presuming the two are moving at the same speed initially, two things could happen to make the momentum the same:


1. The bowling ball would have to slow down

2. The ping pong ball would have to speed up


just remember, as was stated, p=m*v




Have homework questions in chemistry, physics or math?

Basically the speed of the ping-pong ball would have to equal the speed of the bowling ball times the ratio of their masses.



speed of ping-pong ball = speed of bowling ball x ( weight of bowling ball / weight of ping-pong ball.)
