A 1470-kg car moving north at 27.0 m/s is struck by a 2165-kg car moving east at 12.0 m/s.

The cars are stuck together. How fast and in what direction do they move immediately after the collision?
____° north of east
____m/s

(1470 x 27) = 39,690kg/m/sec.
(2165 x 12) = 25,980kg/m/sec.

Sqrt. (39690^2 + 25980^2) = 47,436.868
47,436.868/(1470 + 2165) = 13.05m/sec., and direction = a.tan (25980/39690), = 33.2 degrees E of N, = (90 - 33.2) = 56.8 deg. N of E.
