# Circular Motion and Force Problem

## Homework Statement

A man sitting on the edge of his seat on a Ferris Wheel has a mass of 50.0 kg. The Ferris Wheel has a radius r=30m and the ferris wheel completes a single revolution every 20 seconds. Find the force between the man and the chair.

## Homework Equations

FNET=ma
Fg=mg

$$\tau$$=2$$\pi$$r/v
a=v2/r

## The Attempt at a Solution

I found the force of gravity on the man to be 490N. I think the period is 0.05rev/sec so I set up the $$\tau$$ equation to be 0.05=2$$\pi$$(30)/v. I solved for V however and get 3769.91 m/s. It seems like too big of a number. This then gives me a very large acceleration of 473740.71m/s2.
I need to solve for a to plug into my FNET equation in order to find the force on the chair on man.
What am I doing wrong to get these large numbers?

So the force that the man feels as a push from the seat will depend on where he is as he rotates around the wheel. The Force would be a function of $$\theta$$
