2. You stand on a raft of mass 200 kg floating on the surface of water. You are 50 kg. You and the raft are both initially at rest. a) You start running at 3 m/s to the right (with respcct to the water), and maintain that speed. What will the speed and direction of the raft be now? b) After a few scconds, you are now 7 meters to the right of your initial position (rclative to the water). Using what you know about the center of mass of the system, find how much the raft has shifted from its initial position. c) You and the raft both stop. While standing on your raft, a strong gust pushes you and the raft with a time varying force to the right, F(t) = c t, where c = 100 N / s, from t = 0s to t = 5s. What is the total impulse on you and the raft from this gust, and what's the corresponding change in velocity? Assume you stay fixed to the surface of the raft.

a man of mass m1 = 70.0 kg is skating at v1 = 8.00 m/s behind his wife of mass m2 = 50.0 kg, who is skating at v2 = 4.00 m/s. Instead of passing her, he inadvertently collides with her.

(b) How high in the air will the squid rise?
A tennis ball of mass 57.0 g is held just above a basketball of mass 590 g. With their centers vertically aligned, both balls are released from rest at the same time, falling through a distance of 1.20 m, as shown in Figure P6.45. (a) Find the magnitude of the basketballs velocity the instant before the basketball reaches the ground. (b) Assume that an elastic collision with the ground instantaneously reverses the velocity of the basketball so that it collides with the tennis ball just above it. To what height does the tennis ball rebound? Figure P6.45
