A truck is traveling at 70mph and has wheels with a diameter of 26in. Find the angular velocity in radians per minute. Also find in revolutions per minute.

I've attempted this question and am completely stumped. I can't figure out how to make it work with the formula I'm given which is angular velocity=theta(angle)/time

1 answer

one revolution covers 26π inches. Now let's start the conversion.

70mi/hr * 1hr/60min * 5280ft/mi * 12in/ft * 2πrad/26πin = 5686 rad/min
