Question 1045458: A truck with 30inch diameter wheels is traveling at 55mi/h. Find the angular speed of the wheels in radians per minute? And how many revolutions per minute do the wheels make? Found 2 solutions by josmiceli, advanced_Learner:Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! Convert mi/hr to in/min
[ 55 mi/hr ] x [ 1/60 hr/mins ] x [ 5280 ft/mi ] x [ 12 in/ft ] in/min
---------------------------
How many times does the circumference, C, of the
wheel go into this number?
------------------
[ in / min ] / [ in/C ] = [ C/min ] C/min
and
[ C/min ] x [ radians/C ] = radians/min ] radians/min
The angular speed of the wheels is 1,936 radians/min
----------------------
[ revolutions/min ] = [ radians/min ] x [ 1C/radians ]
The wheel makes 308.124 revs/min

convert miles per hour into in/min
the wheel is rotating = in/min
= = inches
So, there are inches per revolution of the wheel.
