4. Blocks of masses 11.0 kg and 25.0 kg hang on opposite sides of a pulley (Atwood’s machine) with a massless string that rotates the pulley without slippage. The mass of the pulley is 1.5 kg and it has a radius of 15.0 cm. The heavier mass is 2.5 m above the ground and the lighter mass is 1.2 m above the ground. Using energy consideration, determine the velocity of the two masses when the heavier mass hits the ground.
