Homework Help: Car collisions

  1. Oct 18, 2011 #1
    If car 1 has a a mass(m) and car 2 has a mass(2m), in a head on collision, with both cars traveling the same velocity, which car experiences a bigger acceleration ?

    my answer - car 1

    If two identical cars with identical speeds and masses collide, the impulse recieved by each car is the same as if one of the cars collided with a wall ?

    my answer - yes

    Car 1 has a mass(m) car 2 has a mass(2m). In a collision while moving with identical velocities, does car 1 receive a bigger impulse than car 2 ?

    my answer - yes

    I'm new to collisions, momentum, and impulse
    If someone could throughly walk me through the problems I would really appreciate it.
    If I'm wrong please point it out, I deff. can't learn from my mistakes without knowing I made any

    Thank you !

    During collision there are equal and opposite forces acting on the cars.

    F = ma_1

    F = 2ma_2

    bigger mass, same magnitude force, less acceleration?
