A car in an amusement park ride rolls without friction around the track it starts from rest at a point A from height H above the bottom of the loop. treat the car as a particle. what is the minimum value of height (in terms of R radius)such that the car doesn't fall off the very top of the ramp.

2. Relevant equations

E=mgh

gravity constant

Fc=.5mv^2

K=.5mv^2

3. The attempt at a solution

i dont really know where to start but ill give it a shot.

2R is the height of the

so mgh-mg2R= 1/2mv^2

i dont really know what else to do -_-

since mgh-mg2R=1/2mv^2 could you assume that v approaches 0 then mgh=mg2R which makes sense to me because if the surface is frictionless then energy is being conserved so does this mean if the height from which it came = the height of what it needed to go to?
