A 21 mm diameter glass marble with a mass of 25 g rolls without slipping down a track toward a vertical loop of radius R=15 cm, as shown in the figure. Approximate the minimum translational speed vmin the marble must have in order to complete the loop without falling off the track when it is a height H=25 cm above the bottom of the loop. H R Figure is not to scale.
