a pool player imports an impulse of 3.2 N*s to a stationary 0.25-kg cue ball with a cue stick what is the speed of the ball just after impact
Answered by drwls
The impulse equals the change in momentum, which is (mass) x(velocity change.

Solve for the velcoity change, which is the same as the final velocity in this case.
