- 3. A rowing machine consists of a solid disk with a radius of 20-cm and a mass of 19-kg. An athlete pulls on the attached cable with a force of 10-Newtons and causes the disk to accelerate. If the disk starts from rest, determine; a. The disk's moment of inertia. b. The magnitude of the torque applied by the athlete. C. The disk's angular acceleration. d. The disk's angular momentum at t = 5.0 sec.40. A ball swings around a pivot at a constant rate due to an applied force. If the applied force is increased by a factor of four in the direction of the pivot, the ball’s angular velocity willA. decrease by a factor of 2.B. increase by a factor of 2.C. decrease by a factor of 4.D. increase by a factor of 4.1. Perform analysis steps B.1. Derive an algebraic equation for the moment of inertia of the disk/plate by using the conservation of energy method. The variables in your equations should be the values you can measure (e.g., mass of hanger, angular velocities, angular acceleration, positions and/or velocities of the falling mass, etc.) and physical constants (i.e., the acceleration due to gravity). You should do this on a separate sheet and keep a copy as you will need it during the lab.
