A hamster is a wheel with wheels inner diameter 1-meter, if it accelerates the wheel at a constant angular acceleration of 8 rad/s 2 for 3-seconds, what is is the final angular speed of the wheel? what is hamster tangential speed, in realtion to hamster wheel after 3 seconds? what is the hamsters centripetal acceleration, when running at full speed on the bottom of the hamster wheel?

A rotating space station is said to create "artificial gravity. a loosely-define term used for an acceleration that would be crudely similar to gravity. The outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. If the space station is 150m in diameter, what angular velocity would produce an "artificial gravity" of 9.80m/s^2 at the rim

A rock is wedged in the tread of wheel of a car and is 0.114 meters away from the center the axis of rotation). Calculate the tangential speed (in meters/second) of the rock when the wheel is rotating at 6.53 revolutions/second. Express your answer without units and as a positive number with two decimals.
