Sobre una pista circular de atletismo de 30m de diámetro, un atleta realiza su recorrido con una velocidad tangencial de 0.5 ft/s Determine su aceleración centrípeta.

a = 0.00154 m/s²

Explanation:

On a circular running track 30m in diameter, an athlete travels with a tangential velocity of 0.5 ft / s. Determine his centripetal acceleration.

The diameter of running track is 30 m

Its radius is 15 m

The tangential velocity of the athlete is, v = 0.5 ft/s = 0.1524 m/s

We need to find the centripetal acceleration of the athlete. The centripetal acceleration is given by :

So, the centripetal acceleration of the athlete is 0.00154 m/s².
