How high above the top of the loop must the cart be released

Reference no: EM13492537

A cart slides down a frictionless inclined track to a circular loop of radius R = 6 m. In order for the cart to negotiate the loop safely, the normal force acting on the cart at the top of the loop, due to the track, must be at least equal to the cart's weight. (Note: This is different from the conditions needed to just negotiate the loop.)

How high h above the top of the loop must the cart be released?
