In the system presented on the above diagram, block 2m and block 3m are connected by a light string passing over a frictionless pulley. Block 2m is placed on the surface of a horizontal table with negligible friction. Present all answers in terms of m, L, and fundamental constants. a) Determine the acceleration of the system after it is released from rest. b) Determine the velocity of the 3m block just before it hits the floor. c) Determine the velocity of the 2m block at the edge of the table.
