A horizontal 650 N merry-go-round is a solid disk of radius 2.75 m. It has an initial angular velocity of 0.5 rad/s and started to accelerate by a constant horizontal force of 70.0 N applied tangentially to the edge of the disk. Find the kinetic energy of the disk after 7.00s. O A 5 93 k O B) 387 O C 361 O D) 432 OE 245
