A massless rope connects two blocks through a frictionless pulley with a moment of inertia I = 0.4 kgm 2 and a radius R = 0.2 m. There's no sliding between the rope and the pulley. The block with mass M 1 = 5 kg slides along a horizontal table as shown in the figure. Coefficient of friction between the block and the table is µ = 0.2. Second block has mass M2 = 4 kg and is placed at height h = 6 m above the ground. The system is released from the rest. Find velocity of the second block just before it hits the ground.
