A bowling ball weighing 71.2 is attached to the ceiling by a 4.00 rope. The ball is pulled to one side and released; it then swings back and forth like a pendulum. As the rope swings through its lowest point, the speed of the bowling ball is measured at 4.20 .
At that instant, find the magnitude of the acceleration of the bowling ball.
=
Part B
At that instant, find the direction of the acceleration of the bowling ball.
Upward
Downward
In the direction of motion
Part C
At that instant, find the tension in the rope.

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.
