Question

Need help on these two questions.

c) If the flywheel is "charged" for 10 minutes from rest, determine its final angular
velocity.
d) Determine the total rotational kinetic energy accumulated by the flywheel during
this time.
e) In a similar car 2.1 x 107 J of energy contained in the flywheel is used to accelerate
(from rest) a car of mass M = 2523.4 kg, determine the final velocity of the car. To
make the calculation easier, ignore the friction between the car and the asphalt
and air resistance. (You simply converting the stored rotational energy to
translational energy)
