Two friends, one at each end of a 4.00 m long raft over water, are playing with a 9.07-kg medicine ball. One of them throws the ball to the other. If the total mass of the people and raft is 131 kg and the viscosity between the water and raft is ignored, how far does the raft move before it comes to a stop again?

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.
