A Merry-Go-Round is moving at а non-varying speed of 10 m/s. It implies that

The correct answer is option 2 i.e. it is moving with uniform acceleration.

Concept:

• Uniform circular motion is where a moving object traces a circular path with constant speed.
  • ​A circle is assumed to be a polygon with infinitely many sides such that each side approximates to a point.
  • So, if the object moving on a circular path undergoes a change in direction at every point.
  • Since direction changes and speed remains constant, velocity is varying at every point.

Explanation:

• The merry-go-round is under a uniform circular motion i.e. it has a constant magnitude of velocity, but the direction of velocity changes at every point.
• A change in velocity is due to a change in magnitude or direction or both.
• Acceleration occurs if there is a rate of change of velocity.
• Since it is moving with constant speed but the velocity changes, it is in uniform accelerated motion.
