You can put this solution on YOUR website! A truck with 48-in.-diameter wheels is traveling at 45 mi/h.
---------
45 mi/hr = 66 ft/sec = 3960 ft/minute
----------
Each revolution = pi*d feet = 4pi feet
(b) How many revolutions per minute do the wheels make?
rev/min
-------------
Each revolution = pi*d feet = 4pi feet
rpm = 3960 ft/min / 4pi feet = 990/pi rpm
=~ 315 rpm
---------------
(a) Find the angular speed of the wheels in rad/min.
rad/min
-------------
rad/min = rpm*2*pi
= 990/pi * (2pi)
= 1980 rad/min
