child and sled to the edge of the hill (point B). At point B, the child and sled have a kinetic energy of 100 J. The combined mass of the child and sled is 20 kg. Use the bar graphs below to indicate the mechanical energy (ME), gravitational potential energy (GPE), and kinetic energy (KE) of the child and sled at points A and B.
