A spherical ball with a mass of 0.050 kg and
a radius of 0.010 m is released from a height h on a track with a circular loop in it, as shown. if the radius of the loop is 0.500 m, what is the minimum value of h so that the ball will stay on the track all the way through the loop? The moment of inertia of a solid sphere about its center isI=2/5MRsquared.
a. 1.65 m
b. 1.25 m
c. 2.00 m
d. 1.35 m
