Trucks can run on energy stored in a rotating flywheel with an electric motor getting the flywheel up to its top speed of 847 radians per second. The flywheel is a solid, uniform cylinder with a mass of 461 kg and a radius of 0.939 meters. If the trucks uses an average power of 8.0 kW, for how many minutes can it operate before the flywheel needs to be "charged" again? By "charging" we mean the electric motor adds energy...
A rotating flywheel has been proposed as a means of temporarily storing mechanical energy in an automobile, providing an energy source for the car. The energy that can be stored in this way is limited by the size and weight of the flywheel and by the maximum angular velocity it can attain without flying apart. Suppose a solid cylindrical flywheel of radius 95.0 cm and mass 80.0 kg rotates at a maximum angular velocity of 295 rad/s. Find the maximum...
Trucks can be run on energy stored in a rotating flywheel, with an electric motor getting the flywheel up to its top speed of 627 rad/s.

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 160 rev/s. Assuming all of this stored kinetic energy could be transferred to the linear velocity of the 3200-kg car, find the maximum attainable speed of the car.
