Consider the sketch of part of a roller coaster ride below. At position A, the roller coaster will reach its maximum height, at 10m. Assuming there is no energy loss, write down the total energy (TE), potential energy (PE), and kinetic energy (KE) of the roller coaster at positions A, B, C, and D. The mass of the roller coaster is 100kg, and acceleration due to gravity is rounded to be 10m/s2. Discuss the aspects of energy conservation.
