During a race, the 80kg sled moves from point A to points B and C on an ice rink. Find: a) The potential energy of the sled at points A, B, C with respect to the zero level of potential energy passes through point A. this level. c) The potential energy of the sled at points A, B and C with respect to the zero level of potential energy passing through the points C d) The change in potential energy of the sled when it shifts from point B to C with respect to the second level zero of potential energy
a) In this case:
c) In this scenario:
d) At point B:
