Rotational Kinetic Energy: a Futuristic Design for a Car Is

Short Answer

Rotational kinetic energy: A futuristic design for a car is to have a large solid disk-shaped flywheel within the car storing kinetic energy. The uniform flywheel has mass 370 kg with a radius of 0.500 m and can rotate up to Assuming all of this stored kinetic energy could be transferred to the linear velocity of the car, find the maximum attainable speed of the car.
