Rotational Kinetic Energy: A futuristic design for a car is to have a large flywheel within the car to store kinetic energy. The flywheel is a solid uniform disk of mass 370 kg with a radius of 0.50 m, and it can rotate up to 200 rev/s. Assuming all of this stored kinetic energy could be transferred to the linear speed of the 1500-kg car, find the maximum attainable speed of the car.
