A bicycle wheel of diameter 30 inches is spinning at a rate of 60rpm. What is the exact value of the angular velocity of the wheel in rad/min?
Ans: 60*2(pi)rad/min = 120pi rad/min
---------------------------------------
What is the linear speed of the bicycle in the previous problem to the nearest mile per hour?
Circumference of the wheel is 30pi inches
[3600 rev/hr][30pi inches] = 108000pi inches/hr
--------------
(108000pi in/hr)(1 ft/12 in)(1 mi/5280 ft)
= [108000pi*1*!]/[12*5280] mph
= 5.355 mph
