One possibility for a low-pollution automobile is for it to

One possibility for a low-pollution automobile is for it to use energy stored in a heavy rotating flywheel. Suppose such a car has a total mass of 1400kg , uses a uniform cylindrical flywheel of diameter 1.90m and mass 230kg , and should be able to travel 300km without needing a flywheel "spinup."

Part A Make reasonable assumptions (average frictional retarding force = 500N , twenty acceleration periods from rest to 95km/h , equal uphill and downhill, and that energy can be put back into the flywheel as the car goes downhill), and estimate what total energy needs to be stored in the flywheel. Express your answer using two significant figures.

Part B What is the angular velocity of the flywheel when it has a full "energy charge"?

Part C About how long would it take a 150-hp motor to give the flywheel a full energy charge before a trip?
