Which car lands farthest horizontally from the edge of the cliff to the ground below?

  1. Nov 11, 2008 #1
    1. The problem statement, all variables and given/known data
    Car 1 and Car 2 are initially at rest on a horizontal parking lot at the edge of a steep cliff. Car 1 has twice the mass as car 2. Equal and constant forces are applied to each car and they accelerate across equal distance to the cliff. We ignore the effects of friction. When they reach the far end of the lot, the force is suddenly removed, whereupon they sail through the air and crash to the ground below.


    2. Relevant equations
    Velocity = speed x direction
    inertia
    acceleration = change in velocity/time

    3. The attempt at a solution
    Car 1 has twice the mass it has twice the inertia and less velocity then car 2. Since car 2 has 1/2 the mass, it has greater acceleration leaving the cliff it therefore "shoots out" farther than car 1. Would it be correct to say it has greater "horizontal velocity" leaving the cliff?
