The flywheel of a punch press has a moment of inertia of $$\displaystyle{16.0}{k}{g}\cdot{m}^{{2}}$$ and runs at 300 rev/min. The flywheel supplies all theenergy needed in a quick punching operation.
a)Find the speed in rev/min to which the fly wheel will be reducedby a sudden punching operation requiring 4000J of work.
b)What must the constant power supply to the flywheel (in watts) beto bring it back to it's initial speed in a time of 5.00 s?
