In a crash test, a car runs into a wall and stops. The momentum of the car before the crash is 22500 kg m/s. The car stops in 0.14 s. (i) Calculate the average force on the car during the crash.
Answers
Given
- Momentum = 22500 kg m/s
- Time taken = 0.14 sec
- The force =??
During the car crash the momentum would be transferred , on other hand change in momentum produces Impulse.
Impulse is defined as:
The product of force and time of contact.
Impulse (change in momentum) = force × time
But we have to find force
Force = momentum / time
Force = 22500 / 0.14
Force = 160,714 N
- Is the average force occurred during crash.
