Solve the all parts of given problem:
Problem: A stunt cyclist drives his motorcycle around a loop-the-loop arrangement, with a radius of 13 m. We're going to allow a margin of safety: instead of feeling weightless at the top, the cyclist feels himself pushed into the seat with a force equal to 1/2 his weight, so his speed must be greater than the bare minimum. Remember that the acceleration of gravity is in the same direction as the centripetal acceleration at the top of the loop, and in the opposite direction at the bottom. Also remember that the normal force acting upon him is the force he actually feels.
Part A: Draw the free-body diagram for the cyclist at the bottom, at the top, and at one other position around the loop.
Part B: How fast is he moving at the top of the loop?
Part C: He then drives down the loop, with only gravity acting to increase his kinetic energy and no frictional losses. How fast is he moving at the bottom of the loop?
Part D: Find his centripetal acceleration at the bottom of the loop.
Part E: Find the acceleration that he actually feels at the bottom of the loop.
I need help to find the acceleration that he actually feels at the bottom of the loop.
