Problem 3.15: An object travels along a circular path

Please wait for the animation to completely load.

An object travels along a circular path as shown in the animation (position is given in meters and time is given in seconds). Restart.

  1. At t = 2 s, what is the direction of the velocity of the object?
  2. At t = 2 s, what is the approximate direction of the acceleration of the object? You do not need to give an exact direction, just an approximate direction based on what you know about the direction of the radial component and the direction of the tangential component.
  3. At t = 4 s, what is the direction of the velocity? If it is zero, indicate so.
  4. At t = 4 s, what is the approximate direction of the acceleration? If it is zero, indicate so.
  5. At t = 6 s, what is the direction of the velocity?
  6. At t = 6 s, what is the approximate direction of the acceleration?
