1. Homework Statement
Determine the height h to the top of the incline D to which the 200kg 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. Homework Equations
KE1+PE1=KE2+PE2
3. The Attempt at a Solution
.5mv1^2+mgh=.5mv^2+mgh
.5mv1^2=mgh
0.5v1^2=gh
