A horizontal carousel is rotating around its axis with constant angular velocity w. On the carousel there is a straight track passing through its middle. A cart of mass m is traveling along the track with constant velocity v relative to the carousel. Note that there is friction between the cart and the carousel. FR XR d. In the rotating system, the cart's speed is constant. What is true? Select one: a. The centrifugal force does negative work, and the centripetal force does positive work. b. The centrifugal force does positive work, and the centripetal force does negative work. C. The centrifugal force does negative work, and Coriolis force does positive work. ○ d. The centrifugal, Coriolis, centripetal and the track side does not do work. e. f. The centrifugal force does positive work, and the track side does negative work. The centrifugal force does negative work, and the track side does positive work.
