Asolid 0.6950 kg ball rolls without slipping down a track toward a vertical loop of radius =0.8950 m . what minimum translational speed must the ball have when it is a height h=1.377 m above the bottom of the loop in order to complete the loop without falling off the track? assume that the radius of the ball itself is much smaller than the loop radius . use =9.810 m/s2 for the acceleration due to gravity.
