1. The problem statement, all variables and given/known data A 181 g ball is released from rest H=5.19 m above the bottom of the track shown in Figure. It rolls down a straight 21° segment, then back up a parabolic segment whose shape is given by y=x2/4, where x and y are in m. How high will the ball go on the right before reversing direction and rolling back down? 2. Relevant equations Ki+Ui=Kf+Uf K=mv^2/2 3. The attempt at a solution I am not sure how to start this because everytime i go to one direction i hit a dead end. At the begining it has both Ki=0 and Ui=0 correct? Then at the final it has Kf and Uf right?
