Consider the following experiment: i am standing on the ground (which we shall take to be an inertial frame) beside a perfectly flat horizontal turntable, rotating with constant angular velocity o. i lean over and shove a frictionless puck so that it slides across the turntable, straight through the center o. the puck is subject to zero net force and, as seen from my inertial frame, travels in a straight line. (a) write down the polar coordinates r, ) of the puck as functions of time, as measured in the inertial frame of an observer on the ground. (assume that the puck was launched along the axis =0 at time t = 0. (b) now write down the polar coordinates r', d' pf the [icl as w measured by an observer at rest on the turntable. (choose these coordinates so that o and 6' coincide at time t = 0.) describe and sketch the path seen by this second observer. is the frame of the second observer inertial?
