1. The problem statement, all variables and given/known data A 500kg truck collides head on with a 400kg car. They stick together and continue traveling west at 6.00 meters per second. The truck initially travels at 13.0 meters per second. Calculate the impulse and force for the car given that the time of impact was 0.6 seconds. 3. The attempt at a solution Using the Law of the Conservation of Momentum, I figured out that the car's velocity is 2.75 meters per second and that is as far as I got.
