A ball having mass 522g begins at rest and slides down a frictionless track. It leaves the track horizontally, striking the ground at a distance x = 0.92 m from the end of the track after falling a vertical distance of h2 = 1.14 m from the end of the track.
(i) Determine at what height above the ground does the ball begin to move?
(ii) Determine the speed of the ball if it leaves the track?
(iii) Determine the speed of the ball if it strikes the ground?
