A 22 kg sled is being pulled along the horizontal snow-covered ground by a child using 65 N of force. Starting from rest, the sled attains a speed of 5.0 m/s in 12.0 m. a) What amount of energy was added to the sled by the child? Explain/Show your work. b) What amount of kinetic energy does the sled have after it has moved 12 meters? Explain/Show your work. c) What amount of energy was taken from the sled by friction with the snow? Explain/Show your work. d) Find the coefficient of kinetic friction between the runners of the sled and the snow. Explain/Show your work.
