Answer 1

1. A pitcher exerts 100.0 N of force on a ball with a power output of 450 W. What is the velocity of the ball?
(Points : 3)
4.5 m/s

0.22 m/s

0.45 m/s

450 m/s

Answer 2

first you should know the formula：Power=Force*velocity,then the answer comes out.
P=Power F=Force V=velocity
450W=100N*v
v=450W/100N=4.5m/s
