An automobile tire has a radius of 0.335 m, and its center moves forward with a linear speed of v = 24.1 m/s. (a) Determine the angular speed of the wheel. (b) Relative to the axle, what is the tangential speed of a point located 0.243 m from the axle?

  • physics -

    Circumference=pi*2r=3.14*0.67=2.1=2.1 m.

    Va = 24.1m/s * 6.28rad/2.1m=72.1 rad/s.

  • phys ics -

    b. V = (0.243/0.335) * 28m/s = 20.3 m/s.
