Question

A frictionless puck is slid across a rotating turntable straight through the center O. The table rotates with constant angular velocity ω. a) Write down the polar coordinates r, φ of the puck as functions of time as measured in the inertial frame δ of an observer on the ground. Assume that the puck was launched along the axis φ = 0 at t = 0. b) Write the polar coordinates r 0 , φ 0 of the puck as measured by an observer (frame δ 0 ) at rest on the turntable. Choose these coordinates so that φ and φ 0 coincide at t = 0. Describe and sketch the path seen by this second observer. Is frame δ 0 inertial?
