A roller coaster track is set up so that the coaster starts from rest, falls, and proceeds to go through a loop according to the picture. Ignore friction. The photogates can be used to determine the velocity of the cart.
Using energy conservation, find the minimum height the cart must start from in order to complete the loop.
Need some help working out these equation. Any help is really appreciated!!

PLEASE SHOW WORK!
A roller coaster starts from rest at a height h at the left side of a loop-the-loop, as shown in the figure. It is not attached to the track in anyway, and there is no friction from the track or from air resistance. If the radius of the loop is R = 6.0 m, what is the minimum height h for which the roller coaster will not fall off the track at the top of the loop?...

Determine the exact height h from which a roller coaster cart must be released in order for the normal force exerted on said cart at the top of the loop to equal twice the force due to gravity; i.e. Fx = 2mg (at the top of the loop). Note that the roller coaster cart is made to traverse a vertical (circular) loop with radius R. Assume, for the purposes of this exercise, that the roller coaster cart is released from...

PLEASE ANSWER CORRECTLY THE CORRECT ANSWER IS 46
A roller coaster cart starts at the top of a quarter circular
hill (no friction) of some radius at a speed of 11.8
m/s. At the bottom of the hill it encounters a
horizontal surface with friction and the coefficient of kinetic
friction is 0.55. It travels over that horizontal surface for 8
meters and encounters a frictionless loop with a radius of 23
meters. If it is to just barely make...
