Question
A runner moving at a speed of 7.7 m/s rounds a bend with a radius of 21 m. What is the centripetal acceleration of the runner?
My teacher doesn't explain anything very well and I don't understand how to figure it out.

Use the formula for centripetal acceleration.
a = v²/r
Friction exerts the force or power.
