Answer to Question #970 in Mechanics | Relativity for Nate

Question #970
It takes you all of 0.018s to initially touch and then catch a 0.600kg football travelling at 16.0m/s

a. what is the change in momentum for the football?
b. what is the impulse?
c. what is the force that must be exerted to stop the ball?
Expert's answer
Change in the momentum: Δp = mΔv = 0.6*16 = 9.6 [kg* m/s]

The impulse equals to momentum change: I = Δp = 9.6 [kg* m/s]

The force:
F = mΔv/t = 0.600*16/0.018 = 533.33 [N]
