An electric motor turns a flywheel fthrough a drive belt that joins a pulley on the motor and a pulley that is rigidly attached to the flywheel. The flywheel is a solid disk with a mass of 50.0kg and a diameter of 1.00m. It turns on a frictionless axle. It's pulley has a mass of 1 kg and a radius of .250 m. The tension on the upper (taunt) segment of the belt is 150 N; the flywheel takes 30 seconds to reach an angular velocity of 430 rpm. Find the tension in the lower (slack) segment of the belt.
