Question

a golf ball of mass 50g travels at 70 m/s hits a persons head ( stopping in 0.05 second ), what is the impact force

Answer 1

Given:

m= 50 g =0.05 Kg

Velocity= 70m/s

t=0.05 sec

acceleration= velocity/time

acceleration=70/0.05

acceleration= 1400 m/s∧2

Force= mass x acceleration

Force= 0.05 x 1400 =70 N
