A solid marble of mass m=35 and radius r=7 cm will roll without slipping along the loop-the-loop track if it is released from rest somewhere on the straight section of the track. From what minimum height h above the bottom of the track must the marble be released to ensure that it doesn't leave the track at the top of the loop? The radius of the loop-the loop is R=1.30 m.
I don't know where to begin. Any advice?
