Physics

A bus contains a 1500 kg flywheel (a disk that has a 0.55 mradius) and has a total mass of 11000 kg.

m = 1500 kg
r = 0.55 m
mt = 11000 kg
v1 = 19 m/s
v2 = 2.75 m/s

A. Calculate the angular velocity the flywheel must have tocontain enough energy to take the bus from rest to a speed of 19m/s in rad/s, assuming 90.0% of the rotational kinetic energy canbe transformed into translational energy.

B. How high a hill can the bus climb with this stored energy andstill have a speed of 2.75 m/s at the top of the hill in m?
