Question

Collision Effect

An impulse of 130.411 Ns is required to stop a person’s head in a car collision. If the face is in contact with the steering wheel for 0.016 s, what is the force on the cheekbone?

Answer 1

since impulse to the head is F×t = 130.411 Ns, after the head hit the steering wheel, the head will come into a full stop and lose all the momentum, therefore the impulse from the steering wheel is the same as the momentum of the head, so the force is 130.411/0.016 = 8150.7 N.
