1. A 72 kg man is holding a 3 kg medicine ball standing motionless on the ice. He pushes the medicine ball away with a velocity of 3.2 m/s east. What velocity does he move at after he tosses the medicine ball?

2. A 1000 kg car is traveling at a velocity of 7.6 m/s north when it collides with a 1400 kg car traveling at a velocity of 4.5 m/s south. The two cars collide and intertwine in a perfectly inelastic collision. What is the velocity of the coupled cars after the collision?
