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

Correct option is B

The correct answer is it is moving with uniform acceleration.
· 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.
Information Booster
· 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.
