3. A 1576 kg car moving south at 32 m/s is struck by a 1837 kg car moving north at 33 m/s. The cars stick
together in a perfect inelastic collision. How fast and in what direction do they move immediately after
the collision?

Answer:

3.0 m/s north

Explanation:

Take north to be positive.

Initial momentum = final momentum

(1576 kg) (-32 m/s) + (1837 kg) (33 m/s) = (1576 kg + 1837 kg) v

v = 3.0 m/s
