SUMMARY
The centripetal acceleration of a race car traveling around a circular track with a diameter of 1.00 km at a constant speed of 90.0 km/h is calculated using the formula Ac = v²/r. The radius of the track is determined to be 0.50 km (or 500 meters), which is half of the diameter. Substituting the values into the equation, the centripetal acceleration is found to be 16.2 m/s². This calculation is essential for understanding the forces acting on the car during circular motion.
