Compact car and a large truck have a head on collision. Durring collision which vehicle if either experiences:

Question

a. The greater force of impact? Explain.

b. The greater impulse? Explain.

c. The greater chance in momentum? Explain.

d. The greater acceleration? Explain.

Answer 1

Let's suppose it's an inelastic collision, as vehicle collisions tend to be.

A. The forces are equal in magnitude. See Newton 2.

B. Impulse = F*t. Forces and times are equal, so impulses are equal in magnitude.

C. Change in momentum = impulse. Both are the same magnitude.

D. F = ma; a = F/m. The compact car has the greater acceleration.

Answer 2

A truck can run over a car and not even realise it. I know one thing for sure. The car would feel the greater force of pain.
