Paul is pushing the wheelbarrow in his garden to the east. His friend John comes along and starts pushing it in the opposite direction, to the west, with a force that's twice as great as Paul's. What can you say about the motion of the wheelbarrow? A. It will move faster than before, to the east.
B. It will move in the direction of johns push, to the west.
C. It will move with the same speed and in the same direction as before, to the east.
D. It will stop moving immediately.

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.
