Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

a) A flywheel with a diameter of 356 mm accelerates uniformly from rest at a
rate of 2.5 rad/s² for a period of 1.8 minute. It then continues at the maximum
speed attained for a further period of 4.5 minutes, after which it decelerates
uniformly to rest over a final period of 2.8 minutes.
Calculate for the flywheel:
(a)
The maximum angular velocity attained in rad/s and also in rev/min.
(b)
The rate of deceleration during the final period of the motion.
(c) The angle, given in radians, turned through by the flywheel during
its period of acceleration.
