Question

A bumper of a new car is being tested. The 2300 kg vehicle, moving at 15 m/s is allowed to collide with the bumper and comes to rest after 0.54 seconds. What is the average force acting on the bumper during impact?

Answer 1

force=mass x acceleration

acceleration= velocity/time

given that m=2300kg

v = 15m/s

t = 0.54s

f= 2300 x 15/0.54

f =2300×27.777

f=63888.89
