A 0.140 kg baseball is thrown with a velocity of 26.2 m/s.It is struck with an average force of 5000.0 N,which results in a velocity of 37.0 m/s in the opposite direction.How long were the bat and ball in contact?

The impulse-momentum theorem states that impulse equals the change in momentum. Impulse = Force × time, and change in momentum = mass × change in velocity. Solving for time: time = (mass × change in velocity) / Force = (0.140 kg × (37.0 m/s + 26.2 m/s)) / 5000.0 N = 1.77 × 10^-3 s.
