Physics 2210 - Summer 2016 EXAM 3 D Name: Discussion TA: /J ; ^ - ' ; Unid: Discussion Section: r. Ant lony Pantziris 2 Show all Work!! Circle your answer(s). A block of mass m\ 1.00 kg sits atop a plane with coefficient of friction Uk = 0.140 and is connected to a block of mass 7M 2 = 2.00 kg through a string that goes over a pulley of mass M= 4.00 kg and radius R = 0.200 m. The pulley rotates about its axis without friction and the string moves over the pulley without slipping. The system starts at rest and block m falls through a height H = 1.50m. The moment of inertia of the pulley is / = MR 2 /2. (a) (b) (c) [3 pts.J How much mechanical energy is lost due to friction? [13 pts.J Use energy methods to find the speed of the mass after it has fallen the distance H. [4 pts.J What is the acceleration of the blocks? M,R (*) H
