A 2,494-kilogram roller coaster car starts at point A almost at rest. It first runs downhill and then is approaching a hill. At its top, the hill can be described by a circle with radius 9 m.
Find the height required at point A, such that the normal force acting on the car in point B is 73% of the weight.
Make sure to practise how to explain your work and also how to evaluate your result. Draw proper diagrams to support your work.
Below answer with the height.

A car on a roller coaster starts at zero speed at an elevation above the ground of 20.8 m. It coasts down a slope, and then climbs a hill. The top of the hill is at an elevation of 14.77 m. What is the speed, in m/s, of the car at the top of the hill? Neglect any frictional effects; g=9.80 m/s2. A projectile is shot from the surface of Earth by means of a very powerful cannon. If the...
