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?
\n" ); document.write( "Ans: 60*2(pi)rad/min = 120pi rad/min
\n" ); document.write( "---------------------------------------
\n" ); document.write( "What is the linear speed of the bicycle in the previous problem to the nearest mile per hour?
\n" ); document.write( "Circumference of the wheel is 30pi inches
\n" ); document.write( "[3600 rev/hr][30pi inches] = 108000pi inches/hr
\n" ); document.write( "--------------
\n" ); document.write( "(108000pi in/hr)(1 ft/12 in)(1 mi/5280 ft) \r
\n" ); document.write( "\n" ); document.write( "= [108000pi*1*!]/[12*5280] mph\r
\n" ); document.write( "\n" ); document.write( "= 5.355 mph
