Homework Statement



So if a person's apparent weight at the top of a ferris wheel is 0N find the time it takes the ferris wheel to make on rotation.

Then find the apparent weight of a person at the bottom of the ferris wheel for the same person on the same ferris wheel?


Homework Equations



a=v2/r

v=2pi(r)/T

The Attempt at a Solution



So to find the time i did the following.

a=9.8 m/s2
r=50m

9.8=v2/50
v=22.1 m/s

22.1=2pi(50)/T

T=14.2 seconds

Now i am not sure what to do to find the apparent weight of the person when he or she is at the bottom of the ferris wheel. I know i have all the information i need i just am having a little trouble starting :(

I know....

N - mg = m v^2 / r

N = mg + m v^2 / r

but i am not sure how to use these to find the apparent weight....

Can someone give me a little push please :)

Thank you

never mind i got it. It was for the same passenger as used in earlier parts of the problem so i already know his true weight and therefore his mass which allowed me to find his apparent weight at the bottom :)
