What is the acceleration of a body revolving in a circle at uniform speed?

The correct answer is .

Explanation:

In the circular motion, the speed of the body is uniform but the velocity of the body changes as the direction of the body changes in the circular motion. In the circular motion, there is only centripetal acceleration.

The acceleration of a body revolving in a circle is as follows;

Here, is the angular velocity and r is the radius.

The direction of the centripetal acceleration is directed towards the center of the circle.

Therefore,  the acceleration of a body revolving in a circle at uniform speed is .

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
