A person is pulling a sled by using a massless string that is tied to the front of the sled. The string makes an angle of 55 to the horizontal. The sled has a mass of 32 kg. There is a block of wood sitting on the sled. The block of wood has a mass of 2.1 kg. The coefficient of static friction between the block and the sled is 0.75. The coefficient of kinetic friction between the block and the sled is 0.6. There is no friction between the sled and the ground. i) [6 points] Draw a free body diagram indicating all of the forces acting on the sled and define any symbols that you use. ii) [4 points] Draw a free body diagram indicating all of the forces acting on the block of wood and define any symbols that you use
