Consider an object undergoing uniform circular motion, at constant speed v and radius r. In the following questions, carefully does not mean the answer has to be long and wordy, it just means you need to make sure you demonstrate an understanding of the important concept or fundamental law that supports your answer.
a.) Carefully explain why it has an acceleration, and if there is torque on the object.
b.) For this case of increasing speed, is there torque on the object? Carefully explain why.
c.) Now, assume that the object is back to uniform circular motion. While it is circling, a puck with the same mass as the object is placed sos that it will be struck by the rotating object. The collision is perfectly elastic, and the surface is frictionless. Draw a picture showing where the puck is placed, and what its path looks like after it is struck.
d.) What are the two conserve red quantities in this interaction?
e.) For your quantities in part h, rewrite them so they are in terms of Mo, the mass of the rotating object Vio, the initial speed of the rotating object, the final velocity of the puck, Vf, and Vfo, the final speed of the rotating object. No I's should be left. You dod not need to solve these equations.
