1. The problem statement, all variables and given/known data A truck (4 000 kg) runs a red light and enters an intersection travelling at 81 km/h [E]. The truck collides with a car (2 000 kg) that was travelling at 54 km/h [N20oW]. Immediately after the collision the truck was travelling at 60 km/h [N 30o E]. Determine the velocity vector of the car immediately after the collision. 2. Relevant equations I used the law of conservation of momentum. I used the concept that momentum is conserved in each component direction. 3. The attempt at a solution The answer that I got was a velocity of approx 99 km/h [E32S]. Can anyone confirm this?
