DATE: November 25, 2011 DUE: November 30 (at or before 2:00pm), 2011 ENG102, homework set #9. 1. Look at Problem 4/71 on page 315 in the book. a. Solve the problem. We now assume that a = 0 and that the tank is empty at t = 0 . b. Determine the necessary external force. c. How long time does it take to fill the tank with 80kg water? What distance has the tank traveled? d. What is the power supplied to the tank? e. What is the energy loss in scooping the 80kg water? m M m u u 1 2 2 M u m m u 1 2. Look at the figures above. A (very weak) rocket consists of a rocket shell with mass M and one chemical reaction of material that has mass 2 m . The two chemical products each have mass m 1 = m 2 = m and velocity u (relative to the shell) such that their combined momentum relative to the shell M is zero (this is reasonable since the rocket carried this fuel before the chemical reaction. The system immediately after the chemical reaction is shown in the left figure, while the system is shown a bit later to the right. The rocket initially has the velocity
