1. A 50 g ball is released from rest 1.0 m above the bottom of the track. It rolls down a straight 30 degree segment, then back up a parabolic segment whose shape is given by y = 1/4x^2, where x and y are in m.(adsbygoogle = window.adsbygoogle || []).push({});

There is a picture shown too, but I can't figure out how to get it in the post. I figure that enough information is given to understand the problem.

2. KE = 1/2 mv^2

PE = mgy

KEf + Ugf = Ki + Ugi

3. I really don't know what I'm doing, but we know that:

m=.50 kg

yi = 1

xf = 1 / (tan30) = 1.73

I think the question is asking me to find the final y which I could find from the equation of the parabola, but then I need x. I'm just really lost.
