Question

A race car moving on a circular track of radius 20 meters. If car’s speed is 108 km/h, then the magnitude of the centripetal acceleration is​

Answer 1

Answer:

450 m/s²

Explanation:

Speed = V = 108 km/h = 30 m/s

Radius = r = 20 m

Hence....

Centripetal Accln = a = V²/r

= 900/2

= 450 m/s²
