You are designing a rotating metal flywheel that will beused to store energy. The flywheel is to be a uniform disk with radius25.0 cm. Starting from rest at t = 0, the flywheel rotates with constantangular acceleration 3.00 rad/s2 about an axis perpendicular to the flywheelat its center. If the flywheel has a density (mass per unit volume)of 8600 kg/m3, what thickness must it have to store 800 J of kineticenergy at t = 8.00 s?
