Suppose a boy is enjoying a ride on a merry-go-round which is moving with a constant speed of $10\ ms^{-1}$ It implies that the boy is
$(a)$. at rest
$(b)$. moving with no acceleration
$(c)$. in accelerated motion
$(d)$. moving with uniform velocity

Because the boy is enjoying a ride on a merry-go-round which is moving at a constant speed of $10\ m/s$. It implies that the boy is moving in a circular path with a constant speed but the direction will change with respect to the time and that indicates the change in velocity and the change in velocity indicates the accelerated motion.

Therefore, the boy is moving in accelerated motion.

Therefore, option $(c)$ is correct.
