A roller coaster car of mass 250 kg has a speed of vo = 12 m/s at point A, located at a height of h = 15 m. the car can move with no friction acting between points A and B.

a) find the speed of the car when it reaches point B. use energy ideas.

b) once past point B, the car feels a friction force of 2000 N. how far from point B does the car travel before coming to a rest?
