A variable torque is applied to a rotating wheel attime t = 0 and causes the clockwise angular acceler-ation to increase linearly with the clockwise angulardisplacement 0 of the wheel during the next 30 revo-lutions. When the wheel has turned the additional30 revolutions, its angular velocity is 90 rad/s. Deter-mine its angular velocity wo at the start of the inter-val at t = 0.
