Apitcher exerts 100.0 n of force on a ball with a power output of 450 w. what is the velocity of the ball? a. 0.45 m/s b. 450 m/s c. 0.22 m/s d. 4.5 m/s

Answer : The correct option is, (D) 4.5 m/s

Solution :

Formula used :

where,

w = work done

t = time taken

d = displacement

P = power = 450 W

F = force = 100 N

Now put all the given values in the above formula, we get the velocity of the ball.

Therefore, the velocity of the ball is, 4.5 m/s
