Please help me with these questions

A motor speeds up the flywheel with a constant torque of 75 N m.

a. Find the moment of inertia about the axis of rotation of the disk.     

b. Calculate the angular acceleration.      

c. Determine how long it takes the flywheel to reach top speed. 

d. Calculate the amount of energy stored in the flywheel.  

The flywheel is disconnected from the motor and connected to a machine to which it will deliver energy.  Half of the energy stored in the flywheel is delivered in 4.0 seconds.

e.Calculate the average power delivered to the machine by the flywheel.  

Flywheels are large, massive wheels used to store energy. They can be wound up slowly by a motor until they
are spinning. This is a way to store the energy you put into the motor as rotational kinetic energy on the wheel.
The wheel can then release that energy by spinning down while attached to a generator or other device to which it
can deliver energy.
Consider a flywheel that has a mass of 350 kg, a 2.5 m diameter and a maximum angular velocity of 1500 rpm.
Assume the disk has a uniform mass distribution.
@MAX = 1500 rpm
R = 1.25 m
D
M = 350 kg
