A bicyce with 26-inch diameter wheels is traveling at 22 miles/hour. What is the angular speed of the wheels in radians/minute.

Answer 1

I convert everything to SI Units first.

26 in = .33 m

22 mph = 9.834 m/s

ω = v/r

ω = 9.834 m/s / .33 m

ω ≈ 30 rad/s

convert seconds to minutes

30 rad/s * 60 s/1 min = 1800 rad/min
