Question

As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 23.7 m/s. In the process, he moves his hand through a distance of 1.60 m. If the ball has a mass of 0.151 kg, find the average force he exerts on the ball to give it this upward speed. (in N)
A: 2.08 B: 3.01 C: 4.37 D: 6.33 E: 9.18 F: 1.33×101 G: 1.93×101 H: 2.80×101

Explanation / Answer

Applying vf^2 - v0^2 = 2 a d

23.7^2 - 0^2 = 2 (a)(1.60 )

a = 175.5 m/s^2

Fnet = F - m g = m a

F = m (a + g)

F = 0.151 (175.5 + 9.8)

F = 28 N
