1. The problem statement, all variables and given/known data Two cars are initially at rest on a horizontal parking lot at the edge of a steep cliff. Car 1 (HC) has twice as much mass as car 2 (TLC). 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. Which car has the greater momentum at the cliff's edge? 2. Relevant equations Impulse= force x time Momentum= mass x velocity 3. The attempt at a solution Since velocity is a factor of momentum, I would need to figure out the acceleration? However, I don't see that there is enough information to do that. My guess is that since car 1 has twice the mass, but the same force and time, it has more momentum. Car 2, has 1/2 the mass of car one, but the same force and time, so less momentum? This looks right. Anyone know for sure??
