You are trying to solve a problem in which you are given the net force on a cow, the time it is applied, the distance it is moved, and the initial velocity, and you are asked to find the mass of the cow. You think you have solved the problem, but when you check with some study-buddies you find that each one has come up with a different solution! Which solutions can you reject based on a units check.

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.
