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

Answer 1

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.

Answer 2

I got 12.8 m/s, which is 13 m/s after sig figs.
