The figure below depicts a roller coaster track. The roller coaster car has a mass of 166 kg, and the heights of the two hills are h1 = 33.4 m and h2 = 13.1 m. At point A, the roller coaster car has a speed of 9.52 m/s. What is the car's kinetic energy (in Joules) at point C? Friction and air resistance can be neglected.
