Imagine you are riding a 20 meter diameter Ferris wheel that is making three revolutions per minute.

a. What is the linear Velocity?

b. ...angular velocity?

c. There are 8 equally spaced seats on the Ferris wheel, what is the arc length between two adjacent seats?

d. Let H(

*t*) = the height (in meters) at

*t* seconds, where H(0) = 0.

Locate position on Wheel for each time:

0 | 2.5 | 5 | 7.5 | 10 | 12.5 | 15| 17.5 | 20

I'm pretty sure I got a b and c, I just want to check my answers!

I have no idea where to begin with d, please help.
