Question 1091706
A truck covers a distance of 50 meters in an hour. Find the angular velocity (in radian per second) of the truck if the diameter of the tire is 200 meters?
--------------
That's a big tire, and a slow truck.
---
Each revolution covers pi*d meters = 200pi meters.
50 m/200pi m = 1/(4pi) revolutions in 1 hour
--> (1/4pi) rev/3600 sec
= (1/4pi)*2pi rad/3600 sec
= 1/7200 rad/sec
