1. The USA 4-man bobsled team won an Olympic gold medal in 2010. During the race, the winning bobsled and 4 riders reached a maximum speed of 92.4 mph corresponding to a maximum kinetic energy of 539 kJ. The mass of the winning sled (with no riders) was 228 kg a) Determine the average mass of each man on the gold medal USA 4-man bobsled team. b) At the point that the bobsled and riders reached maximum speed, they had already lost 267 kJ of energy to friction and air resistance on the upper section of the course. Use the conservation of energy to determine the vertical height the bobsled and riders had descended at that point
