Colliding Objects (2-D) – Practice
1) A 1500kg car moving north at 7.5 m/s loses control on an icy road and collides with a stationary 2500kg 4WD. They move off in different directions to the original direction. The smaller car slides off road at 4.6 m/s at an angle of N12°W and the 4WD moves off the road at an angle of N30°E. What is the velocity of the 4WD?
1) 2.1 m/s
