1. A 50 kg solid disk (I= ½ mr²) with a radius of 15cm starts from rest and rotates about an axis through its center. It takes 30 rotations to reach an angular velocity of 20rad/s. a) What is the disk's angular acceleration? (4 pts) b) How much time does it take to reach the final velocity? (4 pts) c) What is the net torque on the disk during the acceleration? (4 pts) d) If the net torque is caused by a single force applied at an angle of 45⁰ to the rim of the disk, what is the magnitude of that force? (4 pts)
