Trucks can be run on energy stored in a rotating flywheel, with an electric motor getting the flywheel up to its top speed of 689 rad/s. one such flywheel is a solid, uniform cylinder with a mass of 507 kg and a radius of 1.2 m that rotates about its central axis. what is the kinetic energy of the flywheel after charging

Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.
