Hello I'm trying to review previous work. This question has me a little stumped. What I tried to do is First I draw a circle, then I mark two points on the bottom and top of the circle. Then I draw the force of gravity and the force of the seat pushing up against gravity but how am I suppose to make an equation from this? Quote:

at the bottom of the wheel ... $F_c = N_B  mg$ $\dfrac{mv^2}{r} = N_B  mg \implies N_B = \dfrac{mv^2}{r} + mg$ at the top of the wheel ... $F_c = mg  N_T$ $\dfrac{mv^2}{r} = mg  N_T \implies N_T = mg  \dfrac{mv^2}{r}$
