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?
w (rad/sec)=2PI/12.5 rad/sec
centripetal force=m w^28r=m*(2PI/1.25)^2*30
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
