A 1500-kg car moving north at 27.0 m/s is struck by a 2165-kg car moving east at 13.0 m/s. The cars are stuck together. How fast and in what direction do they move immediately after the collision?

Question

1. what is the degree north of east?
2. how was do they move after the collision (M/S)

Answer 1

The momentum in each direction is conserved.

angle=arctan(momentum N/momentum E)

velocity= (momnetum N + Momentum E)/total mass
