a ferris wheel 42.5m in diameter rotates once every 18.2s. What is the ratio of a person's apparent weight to her real weight at (a) the top and (b) the bottom?

please please PLEASE show all steps and write out all the work I have been stuck on this problem and I can't figure out where I'm going wrong.

Expert Solution

The Ferris wheel rotates once every 18.2 s

Hence, angular velocity is

At each point in the wheel, the person experiences a centripetal force Fa directed towards the center of the wheel.

When the wheel is at the top:

By Newton’s 2^nd law

N1 is the force exerted on the person

Applying Newton’s 2^nd law

This is the apparent weight at the top of the wheel

Ratio of apparent and real weight is hence

When the person is at the bottom:

N2 is the force exerted on the person

Applying Newton’s 2^nd law

This is the apparent weight at the bottom of the wheel

Ratio of apparent and real weight is hence
