A pitcher exerts 100.0 N of force on a ball with a power output of 4,500 W. What is the velocity of the ball? 0.02 m/s, 45 m/s, 450 m/s, or 4500 m/s ?? :/ thank you!

here we have the subsequent relationship between power P, force F and velocity v: \[P = Fv\]

so: \[v = \frac{P}{F}\]

here is next step: \[v = \frac{P}{F} = \frac{{4500}}{{100}}\]
