A Ferris wheel is 60 meters in diameter and rotates once every 12.5s. what is the ratio of a person's apparent weight to her real weight (a) at the top, and (b) at the bottom?

centripetal force=m w^28r=m*(2PI/1.25)^2*30

real weight=mg

apparent weight at top=realweight-centripetal force

apparent weight at bottom=real weight+centripetal force

can you help solve it because i don't understand it

no
