A rocket has total mass Mi = 360 kg, including Mfuel = 330 kg of fuel and oxidizer. In interstellar space, it starts from rest at the position x = 0, turns on its engine at time t = 0, and puts out exhaust with relative speed ve = 1 500 m/s at the constant rate k = 2.50 kg/s. The fuel will last for a burn time of Tb = Mfuel/k = 330 kg/(2.5 kg/s) = 132 s.

The mass of a regulation tennis ball is 57 g (although it can vary slightly), and tests have shown that the ball is in contact with the tennis racket for 30 ms.(This number can also vary, depending on the racket and swing.) We shall assume a 30.0 ms contact time. One of the fastest-known served tennis balls was served by “Big Bill” Tilden in 1931, and its speed was measured to be 73 m/s. Suppose that the positive direction of the x-axis is along the direction of motion of the ball after Big Bill's hit. What is the x-component of the force exerted by Big Bill on the tennis ball in his record serve? If Big Bill's opponent returned his serve with a speed of 55 m/s what is the x-component of the force he exerted on the ball, assuming only horizontal motion?

Ernest Goes Fishing. After putting his fishing gear in the canoe he walks back to his car to lock it. Upon returning he finds that the canoe was not secured properly and is now drifting along the pier parallel to it at 1 m/s, without friction. He runs down the pier at 5 m/s and jumps into the canoe that is moving in the same direction he is. When Ernest has landed in the boat, what is its final velocity (in m/s)? Ernest has a mass of 70 kg and the canoe (with fishing gear) has a mass of 30 kg. Use conservation of momentum for an inelastic collision.
