- A flywheel is a solid disk that rotates about an axis that is perpendicular to the disk at its center. Rotating flywheels provide a means for storing energy in the form of rotational kinetic energy and are being considered as a possible alternative to batteries in electric cars. The gasoline burned in a 341-mile trip in a typical midsize car produces about 3.38 x 10⁹ J of energy. How fast would a 46.2-kg flywheel with a radius of 0.517 m have to rotate to store this much energy? Give your answer in rev/min. Number i UnitsRotational kinetic energy: A uniform solid sphere of mass M and radius R rotates with an angular speed w about an axis through its center. A uniform solid cylinder of mass M, radius R, and length 2R rotates through an axis running through the central axis of the cylinder.

- The ramp on the figure is 0.75 m high. The object is a 2.0 kg cylinder with radius of r = 0.10 m. The cylinder rolls from the top and reaches the bottom. A) What is its total kinetic energy at the bottom? B) What is its rotational kinetic energy, C) what is its translational kinetic energy?Computation. A concept car includes a solid disk-shaped flywheel which can be spun up to store rotational kinetic energy. On demand, that stored energy can be converted into the car's translational kinetic energy. Suppose the flywheel has a mass of 380 kg, a radius of 0.4 m, and maximum rotational speed of 70 rev/s. Calculate the 1,593-kg car's maximum speed (starting from) rest if all of its kinetic energy comes from the flywheel.
