Question

a ball of mass 16 kg on the end of a string is spun at a constant speed of 2 m/s in a horizontal circle with a radius of 1m. What is the work done by the centripetal force during one complete revolution

Answer 1

The work done by the centripetal force during om complete revolution is 401.92 J.

What is centripetal force?

Centripetal force is a force that acts on a body undergoing a circular motion and is directed towards the center of the circle in which the body is moving.

To Calculate the work done by the centripetal force during one complete revolution, we use the formula below.

Formula:

• W = (mv²/r)2πr
• W = 2πmv²................... Equation 1

Where:

• W = Work done by the centripetal force
• m = mass of the ball
• v = velocity of the ball
• π = pie

From the question,

Given:

• m = 16 kg
• v = 2 m/s
• π = 3.14

Substitute these values into equation 1

• W = 2×3.14×16×2²

• W = 401.92 J

Hence, The work done by the centripetal force during om complete revolution is 401.92 J.
