A car on a roller coaster starts at rest at an elevation of 26 m above the ground. It coasts down a slope, and then climbs a hill. The top of the hill is at an elevation of 16 m. What is the speed of the car at the top of the hill? Neglect any frictional effects. [Hint: Use conservation of mechanical energy].
