Homework Statement
[/B]
A 0.145- kg baseball with an initial speed of 20 m/s rebounds with a speed of 36 m/s after being struck with a bat. If the duration of contact between ball and bat was 2.4 ms, what was the magnitude of the average force between ball and bat?
Homework Equations
Δ velocity=Vf-Vi
F= mass* Δ velocity/(Δ time)
The Attempt at a Solution
[/B]
Δ velocity = -36-20 = -56 m/s
mass* Δ velocity/(Δ time) = 56 m/s * 0.145 kg / .0024s
