1. A 45 kg person on a 400 kg boat traveling right at 10 m/s later jumps out of the boat, which results in the boat having a 11 m/s velocity. What was the velocity of the person jumping out of the boat?

2. a) What is the impulse on a 7 kg ball traveling 10 m/s east that hits a wall and subsequently travels west with 5 m/s? (b) A 3 kg baseball traveling east 10 m/s is caught and brought to rest by a receiver. If the contact time is 0.05 seconds, what is the net force on the ball by the receiver?

3. Two billiard balls, ball A and B of mass 3 kg, collide inelastically. Before the collision, Ball A was traveling east at 5 m/s and 2 m/s north and Ball B was traveling north 3 m/s and 2 m/s west. What are the x and y components of Ball A and Ball B's final velocity after they stick together?
