An inexperienced catcher catches a 128 km/h fastball of mass 134 g within 1.01 ms, whereas an experienced catcher slightly retracts his hand during the catch, extending the stopping time to 10.1 ms. What is the average force imparted to the two gloved hands during the catches of the inexperienced catcher?
What is the average force imparted to the two gloved hands during the catches of the experienced catcher?

(Avg Force) = (momentum change)/(time)
= (mass)(velocity change)/(time)

Apply that equation to both situations.

V must be in m/s and mass in kg to get force in Newtons.
