A pulley system is set up as shown in the picture. The blocks are both set up at the same height of 2 meters above the ground, with the pulley itself set up 3 meters above the two boxes. Assume that the pulley has negligible mass, block 1 has a mass m: = 4 kg, and block 2 has a mass m = 6 kg. The pulley system is released. 1. What is the initial potential energy of block mi? 2. What is the initial potential energy of block m? 3. What is the final potential energy of block ms? 4. What is the final potential energy of block m? 5. How fast are the blocks moving when m hits the ground? 772 m ho = 2m
