A 40 g ball is released from rest 2m above the bottom of a track. It rolls down a straight 30-degree segment, then back up a parabolic segment whose shape is given by y=(1/4)x^2, where x and y are in m. How high will the ball go on the right before reversing direction and rolling back down?

Have no clue how to start this problem.
