1. The Kingda Ka Roller Coaster at Six Flags Great Adventure has a beginning height of 140 m. If one car with a passenger has a mass of 120 kg, how much potential energy does that car have?
B) At the bottom of the first hill of Kindga Ka, the roller coaster car is traveling at 42 m/s. How
much kinetic energy does that car have at the bottom of the first hill? (42 m/s is almost 94
mphl)
C) If we assume that the Kindga Ka roller coaster car was not moving at the top of the hill (v = 0 m/s), how much energy was lost to friction and heat between the top and the bottom of the first hill? Hint: Look at how you solved 1). Yor have to use your answers from a) and b).
