A truck with 0.100 m radius tires travels at 24.0 m/s. At how many radians per second are the tires rotating? What is this in rpm?

  • Physics - ,

    Circumference = pi * 2r =
    3.14 * 0.20 = 0.6283 m/rev.

    Va = 24m/s * 6.28rad/0.6283m = 240 rad/s
    = Angular velocity.

    V = 24m/s * 1rev/0.6283m * 60s/min =
    2292 RPM.
