Question 734534
Angular velocity : a trucker drives 55 miles per hour. His truck's tires have a diameter of 26 inches. What is the angular velocity of the wheels in revolutions per second.
***
1 revolution(rev)=circumference  of truck's tires=π*diameter=π*26 inches
{{{Angular velocity=(55 mi/hr)*(5280 ft/mi)*(hr/3600 sec)*(rev/(pi*26 inches))*(12 inches/ft)}}}
cancel out:mi,hr,ft,inches
{{{Angular velocity=(55)*(5280)*(12)/(3600*26pi)=11.85 (rev/sec)}}}
