A ball of radius rs = 0.28 m and mass m =8.0 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 = 15.0 m without falling? Consider that height is measured from the track surface to the center of the ball (see figure). Select one: O a. h> 30.75 m O b. h> 34.42 m O c. h> 42.22 m O d. h> 42.5 m
