Solving the Force of a Ball Struck by a Bat

[midey]

Homework Statement

A 0.25 kg ball moving at 13 m/s is struck by a bat and leaves the bat traveling at 19 m/s in the opposite direction to its initial direction. If contact between bat and ball lasts for 0.01 s what is the average force exerted by the bat on the ball?

Homework Equations

F= MA

The Attempt at a Solution

0.25X (13+19) but then what solution do i use for the time

 

[Doc Al]

Look up the impulse-momentum theorem.

what does acceleration equal .. ??

Change in what / change in what ... ??

Find the initial and final velocities and change in time and u r done. ^^

 

[VesperJazz]

Average force exerted by the bat on the ball = Rate of change in momentum, juz divide what u find with time.
