1. The problem statement, all variables and given/known data A compact car and a large truck collide head on and stick together (perfectly inelastic collison). Which vehicle experiences the larger momentum change? Which vehicle experiences the larger acceleration during the collision? Explain your answers. 2. Relevant equations p=mv I=Ft 3. The attempt at a solution I think that the truck has a larger momentum change because, first of all, it is conserved, so p=pfinal-initial Assuming the velocities are the same, only the mass should affect the momentum. So thats why I thought the truck has a larger momentum change. But I'm not sure..I look at I=Ft and the forces are equal, and so is the time..So would they have equal change in momentum? HELP! thanks!
