Question

A baseball of mass 148g is travelling at 35.0m/s [E] collides with a baseball bat. the collision lasts for 1.10ms. After the collision, the baseball travels at 52m/s [W]. What is the force of the bat on the baseball

Answer 1

Force * time = change in momentum
= .148 (35+52)

.00110 F = .148 (87)
F = 11,705 N

Answer 2

A baseball ( m=150.0g) is traveling at 40.0 m/s.how much work must be done to stop the ball.
