<PRE><B>Question 821685</B>
a truck is moving at a rate of 105 kilometers per hour, and the diameter of its wheel is 1 meter. Find the angular speed of the wheels in radians per minute.
---------
Perimeter of the wheel = pi*d = pi meters
-----
At 105 km/hr the wheel turns (105000/pi) rev/hour = (33422.53) rev/(60 min)
-----
557.04  rev/min
------
Ans: = 557.04*2pi/min = 3500 radian/min
