1. What is the acceleration of a system consisting of two masses, of 200 grans and 215 grams, respectively, tied at the end of a light cord passing over a frictionless pulley of 150 grams mass and 4 cm. radius, if the masses start at the same level from rest?
2. A string is wound on the edge of a disk weighing 2.5 kg and having a radius of 10 cm. The disk is free to rotate about a horizontal axis at its center. Determine the acceleration of the mass and the tension of the string.© BrainMass Inc. brainmass.com April 3, 2020, 6:20 pm ad1c9bdddf
