A 1405-kg car moving north at 27.0 m/s is struck by a 2165-kg car moving east at 10.0 m/s. The cars are stuck together. How fast and in what direction do they move immediately after the collision?

• Physics -

Write two equations of conservation of momentum in both the north-south (y) and east-west (x) directions. There will be two unknowns: the x and y components of the final velocity. Each equation can be solved for one final velocity component. (The combined final mass is 3570 kg)

Get the direction from the ratio of the two final velocity components.
