A truck is moving at a rat of 90 kilometers per hour, and the diameter of its wheels is 1.25 meters. Find the angular speed of the wheels in radians per minute.
Here is what I got so far:
since I need meters I am going to convert kilometers to meters.
so... 90 kilometers * 1000 = 90,000 meters.
Next I need to figure out how many meters is in 60 minutes:
90,000/60 = 1500 meters in 60 minutes
Ok, now I need to find angular speed:
radius = 0.625
I am not sure about this
1500 * 2pi * .625 = 5980.49 radians per minute?
