A 48 g ball is released from rest at h = 1.4 m above the bottom of the track shown in the figure below. It rolls down a straight 30° segment, then back up a parabolic segment whose shape is given by y = 1/4 x2, where x and y are in m. How high will the ball go on the right before reversing direction and rolling back down? Neglect friction.
