The drum has a radius of 25cm. (a) Find wmin, the minimum angular speed at which the drum needs to rotate, so that a t-shirt can remain stuck at some point on the curved edge of the drum as it rotates (hint: in particular, the t-shirt should remain stuck to that point on the drum even when it gets to the top of the drum). (b) Find the linear speed of the t-shirt if the drum rotates at the minimum angular speed that you found in (a). (c) Suppose that the drum starts from rest and reaches the angular velocity that you found in (a); 10 seconds after starting. Assuming that the angular acceleration is constant within these 10 seconds, find the number of rotations made by the drum in this time.
NASA physicians need to know whether the contents of astronauts' skulls (brain, eyes, eardrums, etc.) move so much during rotational maneuvers that injury might be caused. If you are an astronaut in a spinning spacecraft and have an initial angular displacement of 3.14 radians, an initial angular velocity of 3.683 radians per second, and an angular acceleration of 0.02 radians per second squared, what distance will your eyes have traveled around the center of your skull after 26.83 seconds?
