Answer choice d. 10.07

A ball of radius Is = 0.15 m and mass m =1.0 kg rolls without friction on a roller- coaster. From what height should the ball be released so that it completes the loop with radius R = 3.0 m without falling? Consider that height is measured from the track surface to the center of the ball (see figure). h Select one: O a. h > 8.35 m O b. h > 8.50 m ? O c. h > 9.68 m
