Question

A solid marble, a solid disk and a hoop have the same mass (M = 0.5 kg) and the same radius. Each object is held at rest at the same height and then released. At the bottom of the ramp is a loop-the-loop of radius 1.6 m

What is the minimum height that the marble, disk and hoop can be released so that all three will safely make it around the loop-the loop?

At the top of the loop-the-loop, what is the force the track exerts on the hoop when released at the minimum height?

At the top of the loop-the-loop, what is the force the track exerts on the marble when released at the minimum height?

At the top of the loop-the-loop, what is the force the track exerts on the disk when released at the minimum height?
