Problem 3.17: Uniform circular motion of a wheel

Please wait for the animation to completely load.

A point (red) on a rotating wheel is shown in the animation (position given in meters and time given in seconds). Restart.

  1. What is the period of the wheel (the time it takes the red point to complete one revolution)?
  2. What is the speed of the red point?
  3. What is the magnitude of the acceleration of the red point?
  4. At t = 5.0 s, what is the direction of the velocity vector and what is the direction of the acceleration vector for the red point?
