Question

A car of 15 kg is traveling on a circular track. If the radius of the track is

7. 8 m and the period is 8. 5 seconds, what's the centripetal force on

the car? (Round to the nearest hundredth)

Answer 1

The magnitude of the centripetal force on the car is 69.6 N.

What is centripetal force?

This is a force acting on a body in circular path and it is directed to the center around which the body is moving.

To calculate the centripetal force on the car, we use the formula below.

Formula:

• F = m(4π²/t²)........ equation 1

Where:

• F = Magnitude of the centripetal force on the car,
• m = mass of the car
• t = time

From the question,

Given:

• m = 15 kg
• t = 8.5
• π = 3.14

Substitute these values into equation 1

• F = 15(4×3.14²/8.5²)
• F = 69.6 N

Hence, the magnitude of the centripetal force on the car is 69.6 N.
