A bus contains a 1440 kg flywheel ( a disk that has a 0.670 m radius ) and has a total mass of 9400 kg. Calculate the angular velocity of the flywheel must have to contain enough energy to take the bus from rest to a speed of 17.0 m/s, assuming 89.0% of the rotational kinetic energy can be transformed into translational energy.
How high a hill can the bus climb with the stored energy and still have a speed of 2.90 m/s at the top of the hill? Explicitly show how you follow the steps in the Problem Solving Strategy for Rotational Energy.
