A 2500-kg car moving east at 100 ms collides with a 3000-kg, Ask an Expert

Academics

A 2,500-kg car moving east at 10.0 m/s collides with a 3,000-kg car moving north. The cars stick together and move as a unit after the collision, at an angle of 31.0° north of east and at a speed of 5.30 m/s. Find the speed of the 3,000-kg car before the collision.

=_______ m/s north
