**1. Homework Statement**

A Cadillac of mass 2250 kg going east collides with a Geo of mass 1180 kg headed north on a level highway. The cars remain tangled and slide to rest after traveling 25 m in a straight line at an angle of 20° north of east. The coefficient of kinetic friction for the tires on the road is 0.2. How fast was the Cadillac traveling before the unfortunate collision?

**2. Homework Equations**

Frictional Force = coefficient of friction x normal force, inelastic collision, conservation of momentum, motion formulas.

**3. The Attempt at a Solution**

Did not know how to approach problem.

Thanks for the help
