R You are building a display for a children's science museum in which a uniform, solid sphere of radius 0.079 m starts at rest at the top of a "hill" and rolls, without slipping, down a track and around a loop-the-loop of radius R= 1.32 m. You have already determined that the ball has to be moving at a speed no less than 12 m/s at the top of the loop in order to make it around the loop without falling. Note: You should consider whether the ball will be above or below the track at the top of the loop. What is the minimum height of the "hill" in order to ensure that this happens?
