You are sitting on the edge of a merry-go-round ofradius 1.80m. When you are at the northern-most point of your motion,you have clockwise angular velocity of 30.0rpm and you start to drag your foot on the ground. By the time you have made half a revolution, you aremoving with angular velocity 15.0rpm. Assume constant angular acceleration.

a)What is the magnitudeand direction of your linear acceleration when it isat the southern-mostpointof its trajectory,after making half of arevolution?

b)If you continue to drag your foot, when and where does the merry-go-roundstop?
