Question

"A toy airplane flies clockwise at a constant speed in a horizontal circle of radius 8.0 meters. The diagram shows the path of the airplane as it travels around the circle. WHAT IS THE DIRECTION OF THE VELOCITY WHEN THE ACCELERATION IS SOUTHWARD?

2 Answer

  • When the acceleration is south, the plane is moving east.
  • Answer:

    The direction of the velocity will be towards east.

    Explanation:

    When an object moves in a circle then its velocity is towards the tangent to the circular path and its acceleration is always towards center of that circular path. If we observe the figure attached, when the airplane is at the top its acceleration will be towards south (towards the center of circle) then its velocity direction will be towards east (tangential to circular path).
