pitcher exerts 100.0N of Force on a ball with a power output of 450 W. What is the velocity of the ball

Power is defined as the amount of work over a certain amount of time. Work is also Force times the distance traveled. Simplifying the expression makes it Power=Force x Velocity. Since we are given that the power is 4500 W and the force is 100 N, dividing the Power by force gives 45 m/s, which is the velocity of the ball.

Power = Force * velocity

450 = 100V

V = 4.5 m / s
