A skateboarder, just learning to use a half pipe as shown below, drops in off the top of
one side. She stands straight as she skates down the one side and up the other. She
expected to get to the top of other side but didn't make it. The skateboarder recalled
the law of conservation of energy from science and didn't understand why she didn't
make it to the top of the other side. She then watched some more experienced skaters.
She noticed that they bent their knees and pushed off at the bottom.
Explain why the skateboarder did not make it to the top of the other side of the half
pipe. In your reponse, be sure to include:
the law of conservation of energy
where energy was lost as the skateboard moved across the half pipe.
why the other skaters were able to make it to the top.

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.
