The diameter of ferris wheel is 185 feet, and one complete revolution takes 14 minutes. Find the linear velocity of the person riding on the wheel. Give your answer in miles per hour

Question

anonymous · Answer

omega = 2 pi /14 min
r=d/2
V = r*omega = (2 pi *185 ft/2) / 14 min
                         =pi*185 ft /14 min
convert to mph

This may help you do the conversion...it's the other way but the steps are basically the same: http://openstudy.com/study#/updates/506241b8e4b0583d5cd30d91

Im still slightly confused

anonymous · Answer

im trying to take it from ft/min to mph

anonymous · Answer

$$\frac{ feet }{ minute}* \frac{ 1 mile }{ 5280 feet } * \frac{ 60 minutes }{1 hour }$$

anonymous · Answer

ie multiply by  60/5280

anonymous · Answer

im confused there because i plugged everything in and I got 11100/73920

anonymous · Answer

I think you forgot the "PI"

anonymous · Answer

still didnt work but thank you for trying

anonymous · Answer

how exactly didn't it work?

anonymous · Answer

i got .22mph and its supposed to be either .53mph, .49mph, .38mph, .65mph, or .47mph

anonymous · Answer

it's .47

anonymous · Answer

multiply  11100/73920   by pi

anonymous · Answer

ooooooh i got it! thank you!
