Complete Question:

On a circular race track with a radius of 3.23 km, a certain road car set a speed record of 372 km/h. What was the car's centripetal acceleration?

Centripetal acceleration = 3.306 m/s²

Explanation:

Given the following data;

Radius, r = 3.23 km to meters = 3.23 * 1000 = 3230 m

Velocity = 372 km/h to meters per seconds = 372*1000/3600 = 103.33 m/s

To find the centripetal acceleration;

Centripetal acceleration = velocity²/radius

Centripetal acceleration = 103.33²/3230

Centripetal acceleration = 10677.09/3230

Centripetal acceleration = 3.306 m/s²

answer: a. same unit
