As part of an experiment in physics lab, small metal ball of radius r = 2.4 cm rolls without slipping down a ramp and around a loop-the-loop of radius R = 3.7 m. The ball is solid with a uniform density and a mass M = 396 g.
1)
How high above the top of the loop must it be released in order that the ball just makes it around the loop?
m
2)
Now instead of a sphere, what if we rolled a solid disk with the same mass and radius. How high above the top of the loop must it be released in order that the disk just makes it around the loop?
m
3)
Finally, what if we had allowed a block with the same mass as the sphere to slide on the ramp. The block slips without friction but does not rotate. How high above the top of the loop must it be released in order that the block just makes it around the loop?
m

Problem 9 m,r A solid ball of mass m and radius r sits at rest at the top of a hill of height H leading to a circular loop-the loop. The center of mass of the ball will move in a circle of radius R if it goes around the loop. The moment of inertia of a solid ball is Ibull--mr. (a) Find an expression for the minimum height H for which the ball barely goes around the loop, staying...

I just need help with part c) please/thank you A solid brass ball of mass 20.9 g and radius 8.37 mm rolls smoothly along a loop-the-loop track when released from rest from a tall ramp leading to the loop-the-loop. The circular loop has a 12 cm radius.
