    Physics question regarding angular speed
    Here's the question-please show your work, thank you.

    A Wheel is rolling without slipping at 487 meters per second to the right on a level surface. The diameter of the wheel is 100 centimeters. What is the angular speed of the wheel in revolutions per minute?

    Divide the linear velocity of by the crcumference of the wheel - that will give you revolutions per second. Then multiply by 60 to get RPM.

    By the way - 487m/s is faster than the speed of sound!

When using the Speed= distance/time how would one go about plugging numbers in if the question in a wheel has the diameter of 7 and rotates 1700 revolution per minute. I know you use the Circunfrace which is 14pie then what do you do about the 1700 revolutions; where does that fit in? If any one...
