### 'Net torque equals I alpha' As mass m descends it rotates the cylinder with angular acceleration.

A uniform cylinder, mass M= 25 kg, radius R= .75 m, is mounted on a fixed, frictionless bearing. From a cord wrapped on its surface a mass m=6.4 kg descends and rotates the cylinder with angular acceleration 'A'. See attachment for picture of the apparatus. a. Find the angular acceleration of the cylinder. b. Find the tension
