From the information above this is what I did...

w=3.2 RPM and I changed it to 6.4 rad/min

Radius=45 ft

t= 16 secs and I changed it to 4/15 mins

and I'm suppose to plug it in into this formula right?

x(t)=rcos( θ+wt)

y(t)=rsin( θ+wt)

I need help finding theta

**drwls**, Saturday, November 28, 2009 at 9:46am3.2 rev/min = 20.1 rad/min. You forgot the factor pi

If she is moving at this rate, and the rate is constant, it should take

(1/2)(1/3.2) = 1/6.4 minutes = 9.4 seconds to go from the bottom to the top of the wheel. Something is inconsistent with the numbers you have been given
