Question

A ball of 12 kg is attached to a string of 0.8 meter spun at 4
m/s. What is the centripetal force?

Answer 1

Answer:

240 N

Explanation:

Answer 2

The Centripetal force of the spun ball is 240 N.

The Centripetal force can be calculated using the formula below.

Formula:

• F = mv²/r........................ Equation 1

Where:

• F = centripetal force
• m = mass of the ball
• r = radius
• v = velocity.

From the question,

Given:

• m = 12 kg
• v = 4 m/s
• r = 0.8 m

Substitute these values into equation 1

• F = 12(4²)/0.8
• F = 240 N

Hence, The Centripetal force of the spun ball is 240 N.
