A Cadillac of mass 2220 kg going east collides with a Geo of mass 1210 kg headed north at 25 km/h on a level highway. The cars remain tangled and slide to rest, producing a skid mark 35 m in length. The coefficient of kinetic friction for the tires on the road is 0.2.

How fast was the wreckage (tangled cars) moving right after collision?
km/h
What is the direction of the skid mark?
° north of east
How fast was the Cadillac moving before the collision?
km/h
