Circular Motion Help Please!

[HawKMX2004]

The question states that in an amusement park the Ferris wheel rotates at .4 rad/s An 80 kg man sits on a scale as he rides at a distance of 9 m from the axis of rotation. What does the scale read when the man is A.) At the top of the ride and B.) at the bottom of the ride.

All me and my partner have is that the Velocity of the ferris wheel is 3.6 m/s. We are at a total loss for the rest. Help Please?

Start by seeing how much centripetal force is required for the man to remain in circular motion with the ferris wheel. Consider how this lack of centripetal force affects the resultant force of it and gravity at the top and bottom of the ferris wheel.
