Question
A 0.145 kg baseball pitched at 34.5 m/s is hit on a horizontal line drive straight back at the pitcher at 44 m/s. If the contact time between bat and ball is 5.0 x 10^-3 s, calculate the magnitude of the force (assumed constant) exerted on the ball by the bat A 0.145 kg baseball pitched at 34.5 m/s is hit on a horizontal line drive straight back at the pitcher at 44 m/s.

given
m = 0.145 kg
v1 = -34.5 m/s
v2 = 44 m/s
dt = 5*10^-3 s
F = ?
use Impulse-momentum theorem
Impulse = change in momentum
F*dt = m*(v2 - v1)
F = m*(v2 - v1)/dt
= 0.145*(44 - (-34.5))/(5*10^-3)
= 2276 N
