A roller coaster car of mass 1500-kg starts from rest at an elevation of 35.0 m high and rolls down and then up another incline of lower height 18.0 m. (a) How much potential energy does the roller coaster have at the starting position? (b) How much kinetic energy does the roller coaster have at the starting position? (c) Find the total energy of the roller coaster. (d) How much potential energy does the coaster have at the lower elevation? (e) How much kinetic energy does the coaster have at the lower elevation? (f) How fast is the coaster traveling?
