Did you know?
Did you know that in order to calculate the centripetal acceleration of a race car going around a circular track, you need to know the diameter of the track and the car's speed? For example, if a race car is traveling at a constant speed of 104 km/h around a circular track with a diameter of 1.00 km, the car's centripetal acceleration can be calculated. By converting the speed to meters per second (104 km/h = 28.9 m/s) and using the formula a = v²/r, where v is the velocity and r is the radius of the track (since radius = diameter/2), the centripetal acceleration can be determined. So, if the diameter of the track is 1.00 km, the radius would be 0.50 km (500 m), and when the velocity is 28.9 m/s, the car's centripetal acceleration would be 167.8 m/s².
