Question

Hello! Suppose a boy is enjoying a ride on a merry go round which is moving with a constant speed of 10m-1. It implies that the boy is
A) at rest
B) moving with no acceleration
C) in accelerated motion
D) moving with uniform velocity.
(please answer the following questions)

Answer 1

Answer: in accelerated motion, as we know that the direction of the body is changing at every point and if direction changes the velocity also changes. so to keep a constant velocity, the boy has to accelerate constantly which he is doing.

Answer 2

1. in accelerated motion

2. moving with uniform velocity.

Explanation:

In merry go round, it moves in a circular path and the path covered is called uniform circular motion. In this type of motion, the boy moves with constant speed but the direction is changing rapidly. In other words we can say that the velocity is keep on changing. We know that the rate of change of velocity is called acceleration. So, acceleration also changes.

Hence, it implies that the boy is :

1. in accelerated motion

2. moving with uniform velocity.
