A wheel of radius 0.5 m rotates with a constant angular speed about an axis perpendicular to its
center. A point on the wheel that is 0.2 m from the center has a tangential speed of 2 m/s.

(a) Determine the tangential speed of a point 0.4 m from the center of the wheel.

(b) Determine the tangential acceleration of the point that is 0.2 m from the center.

    Use the .5m radius to calculate the moment of inertia. Use the radius of .4 (or on b of .2) to find tangential speed (w*r)

  • physics -

    What is the role of Moment of inertia here?
    Am I right if I say that the tangential speed is the same 2 m/s & the tangential acceleration zero ?

  • physics -

    You are correct. moment of inertia is not in the picture, acceleration tangential is zero. Good point.
