(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Determine the height h to the top of the incline D to which the 200-kg roller coaster car will reach, if it is launched at B with a speed just sufficient for it to round the top of the loop at C without leaving the track. The radius of curvature at C is

ρC = 25 m. I have attached a picture of this problem below.

2. Relevant equations

KE1+PE1=KE2+PE2

3. The attempt at a solution

.5mv1^2+mgh=.5mv^2+mgh

.5mv1^2=mgh

0.5v1^2=gh
