प्रश्न
A boy is sitting on a merry-go-round which is moving with a constant speed of 10 m s−1. This means that the boy is :
विकल्प
at rest
moving with no acceleration
in accelerated motion
moving with uniform velocity
उत्तर
in accelerated motion
Acceleration is the rate of change of velocity, and the velocity of the merry-go-round is changing with respect to time. Thus, it will move in an accelerated motion.
