a 420 gram football is thrown horizontally at 50mph. if the QB takes .2 s to throw the ball, what is the magnitude of the ball just after it is thrown and what is the magnitude of Annette force on the ball during the throw?
Homework Answers
Given that,
m = 420 gm = 0.42 kg
v = 50 mph = 22.35 m/s
(a)
Magniude of momentum of bal,
P = mv
P = 0.42*22.35
P = 9.38 kg.m/s
(b)
Change in momentum, deltaP = 9.38 - 0 = 9.38
force on the ball during the throw,
F = deltaP / t
F = 9.38 / 0.2
F = 46.93 N
