Determine the impulse required to stop a 0.145-kg baseball moving at 35.7 m/s.*hint: the baseballs initial velocity is 0 m/s. Use the equation impulse-mass(final velocity - initial velocity)
If this impulse is delivered to the ball in 0.020 seconds, then what is magnitude of the force acting between the bare hand and the ball?
Impulse= force x time= change in momentum = mass x change in velocity
