Question

A circular track has a radius of 32.7 m. What is the centripetal acceleration of a runner moving at the rate of 6.2 m/s?

Answer 1

Given: Radius r = 32.7 m;  Velocity V = 6.2 m/s

Required: Centripetal acceleration ac = ?

Formula: ac = V²/r

               ac = (6.2 m/s)²/32.7 m   

               ac = 1.18 m/s²
