Question

A bowling ball of mass 6.8 kg moves in a
straight line at 3.08 m/s.
How fast must a Ping-Pong ball of mass
1.391 g move in a straight line so that the two
balls have the same momentum?

Answer 1

remember

momentum= mass x velocity

Answer 2

first find the momentum of the bowling ball
P= (6.8)(3.08)
=20.944

Answer 3

next, convert the mass of ping pong ball to kg by dividing by 1000
and get 0.001391kg

and since its the same momentum, itll be 20.944

plug it into formula

20.944= (0.001391)v

divide both sides by 0.001391 to find v
