Question 258995
a truck is moving at a rate of 90 kilometers per hour, and the diameter of its wheels is 1 meter. find the angular speed of the wheels in radians per minute. 
:
Circumference of the wheel
C = {{{pi*1}}}
: 
{{{(90*1000)/60}}} = 1500 meters/minute
:
Find rpm
{{{(1500/pi)*(2pi)}}} = 3000 radians/minute
