A small toy car of mass m slides with negligible friction on a ''loop'' the loop track as shown in Fig.3E.32. The toy car starts from rest at a point H above the level of the lowest point of the track
(a) If `H = 2R`, what normal force is exerted by the track on the toy car at point q?. What are the speed and normal force at point r ?
(b) At what height will the ball leave the track and to what maxiumum height will it rise afterwards ?
(c) If `H = 4R`, what is the speed and normal reaction reaction at point s ?
