Question: 7. A sledge loaded with bricks has a total mass of 18.0 kg and 13. A 70-kg base runner begins his slide into second base

7. A sledge loaded with bricks has a total mass of 18.0 kg and 13. A 70-kg base runner begins his slide into second base is pulled at constant speed by a rope inclined at 20.0 when he is moving at a speed of 4.0 m/s. The coefficient above the horizontal. The sledge moves a distance of of friction between his clothes and Earth is 0.70. He slides 20.0 m on a horizontal surface. The coefficient of kinetic so that his speed is zero just as he reaches the base. friction between the sledge and surface is 0.500. (a) What (a) How much mechanical energy is lost due to friction is the tension in the rope? (b) How much work is done by acting on the runner? (b) How far does he slide? the rope on the sledge? (c) What is the mechanical en- ergy lost due to friction
