A truck is moving at a rate of 85 kilometer per hour, and the diameter of its wheel is 1 meter. Find the angular speed of the wheels in radians per minute.

Question

anonymous · Answer

angular speed =linear speed /radius
here radius=1m and linear speed =85km/hr =85*1000/60 metres/minute

anonymous · Answer

85*1000/60 is approximately equal to 1417 meters/minute.  What do I do from here? 

Angular speed = central angle/time??

anonymous · Answer

if ur calculation is right it will be 1417 radians /minute

anonymous · Answer

That's it? Lol, $$Angular Speed = central \angle \div time$$

$$\Theta \div t$$

anonymous · Answer

I feel like 1417 meters/minute is not enough. Haha
