Aflywheel 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 443-mile trip in a typical midsize car produces about 2.67 x 10^9 j of energy. how fast would a 38.3-kg flywheel with a radius of 0.363 m have to rotate to store this much energy? give your answer in rev/min.

You are driving to the grocery store at 20 m/s. you are 110m from an intersection when the traffic light turns red. assume that your reaction time is 0.50s and that your car brakes with constant acceleration. how far are you from the intersection when you begin to apply the brakes? what acceleration will bring you to rest right at the intersection? how long does it take you to stop after the light changes? the known values: vi=20m/s xi=110m t=.50s vf=0m/s xf=0m a=?
