A disabled sailboat is drifting on a current that is moving at 3 miles per hour. Fortunately, it's drifting towards a Coast Guard station 47 miles away, which picks up the distress call and sends a rescue craft directly towards the sailboat. The rescue craft can travel 40 miles per hour. How long will it be before the two vessels meet?

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.
