Given :
Diameter of wheel = 32 inch
Radius = 32/2 = 16 inch
Speed = 60 mph
Now, converting 60 mph in in /min
60 × 63360/60 = 63360 in/min
Angular Speed of Wheel = 63360/16
= 3960 rad/min
Revolution per minute = 3960/ 2π
= 630 rpm
Hence, Angular Speed of wheel is 3960 rad/min and revolutions per minute is 630.
