Problem Statement 1. A pulley of mass mp and radius R is attached to the edge of a table. A string of negligible mass is hung over the pulley and attached on one end to block 2 of mass m2 which hangs over the edge of the table. The other end is attached to block 1 of mass m₁ which then slides along the table. The coefficient of kinetic friction between the table and block 1 is μk. At time t = 0 the blocks are released from rest. Assume mass 2 is large enough that the system accelerates. mi m2 LAST WEEK YOU DID THESE Set Up the Problem: • • Establish an appropriate coordinate system(s) and draw a free body diagram for each block. Draw an extended free-body diagram for the pulley. An extended diagram, often called a torque diagram, shows: o The axis of rotation the point of application of each force ○ and their distance from the axis of rotation. Identify any torques caused by those forces and the signs of the torques. Is the tension the same in each segment of the rope? Why or why not? Set Up Equations: Write the Newton's Second Law equations for m₁, . Write the Newton's Second Law equation for m2, • Write the Rotational Newton's Second Law equation for the pulley. How are the accelerations of the blocks related? How are they related to the angular acceleration of the pulley?
