Answer to Question #337078 in Physics for Simon

Question #337078

A 50 N force is used to push a 0.65 kg metal ball from rest. If the force is applied on the ball for 0.25 seconds, what will be its final velocity?

Expert's answer

\Delta p=m\Delta v=F\Delta t

v_f=F\Delta t/m=50*0.25/0.65=19.2\:\rm m/s
