In the figure, two blocks, of mass m1 = 308 g and m2 = 378 g, are connected by a massless cord that is wrapped around a uniform disk of mass M = 513 g and radius R = 11.1 cm. The disk can rotate without friction about a fixed horizontal axis through its center; the cord cannot slip on the disk. The system is released from rest. Find (a) the magnitude of the acceleration of the blocks, (b) the tension T1 in the cord at the left and (c) the tension T2 in the cord at the right.

Two blocks of mass m1 and m2 > m1 are drawn above.
Two blocks of mass m1 and m2 > m1 are drawn above. The block m1 sits on a frictionless inclined plane tipped at an angle θ with the horizontal as shown. Block m2 is connected to mı by a massless unstretchable string that runs over a massless, frictionless pulley to hang over a considerable drop. At time t = 0 the system is released from rest. a) Draw a force/free body diagram for the two masses. b) Find the magnitude of the...

Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane
Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane and connected with a massless unstretchable string running over a massless, frictionless pulley to M2, which is hanging over the ground. The two masses are released initially from rest.
