A small block of mass m slides along the frictionless loop the loop track shown below. If it starts from rest at point A, what is the speed of the block at point B? (v = squareroot (10 g R)) What is the net force acting on the block at point C? (Don't forget the gravitational force. (F = -mg (8i + j) At what height above the bottom should the block be released so that the normal force exerted...
