A test chamber for astronauts rotates about its centerline at constant angular speed ω1 as the entire assembly rotates about the bearing axis at angular speed ω2, which also is constant. An astronaut is seated securely in the chamber at center point O, which is collinear with both axes of rotation. Ball C falls freely after being released at t = 0 from height H, so the vertical distance from the observer to the ball is Z = H − gt2/2. At t = 0 the plane containing the two rotation axes is horizontal. Determine as a function of elapsed time t the velocity and acceleration of the ball as seen by the astronaut.
