Question

suppose a boy is enjoying a ride on a marry–go–round which is moving with a constant speed of 10m/s. It implies that the boy is : (a) At rest (b) moving with no acceleration (c) In accelerated motion (d) moving with uniform velocity​

Answer 1

Answer:

(c) In accelerated motion

Explanation:

Since position of the boy is changing with time, he is not at rest.

As the path of the ride is circular, his direction is changing at every instance. So, he is moving with non uniform velocity (because velocity is a vector quantity: dependent upon direction).

Since velocity is non uniform, motion is accelerated.
