A cаrnivаl gаme cоnsists оf a ball оf mass = [m] g launched by a spring of spring constant = [k] N/m into a frictionless half-circle loop of radius = [R] cm, as shown here. The ball lands a distance = [d] cm to the left of the half-circle. (Q27 ans 2 pts, Q28 work 5 pts) How long is the ball in freefall after it leaves the half-circle and before it again hits the ground? (Q29, 7 pts) What is the speed of the ball as it leaves the top of the half-circle? (Q30, 7 pts) With what magnitude of force is the track pushing down on the ball right before the ball leaves the track? (Q31, 7 pts) What is the speed of the ball after it is launched from the spring but before it gets to the half-circle? (Q32, 7 pts) What must have been the compression of the spring to make this happen? To continue, please give the time in the air (part a) in units of ms.
