... The astronaut's mass is 60 kg and the panel's mass is 80 kg. Both the astronaut and the panel initially are at rest relative to the telescope. The astronaut then gives a panel a shove. After the shove it is moving at 0.3 m/s relative to the telescope. What is her subsequent velocity relative to the ...

... So we see that the (x, y) part of the trajectory is a circle that may be offset from our coordinate system. However, choosing our coordinate system origin to be the center of the circle, we simply have: x x iy Ceiwt Note, however, that the position at t = 0 is not zero, but rather is x (0) ...
