Fareza decides to take advantage of the snow and perform “doughnuts” in the school parking lot.  If the speed of Fareza’s car is 20 m/s and she creates a circle with a radius of 20 meters, determine Fareza’s centripetal acceleration.

radius = 20 m        speed = 20 m/s

Ac = V^2 / R

Ac = (20)^2 / 20

Ac = 400/20

Ac = 20 m/s^2

Speed = 20m/s    r = 20m    Ac = ?

Ac = V² / r

     = 20² / 20

     = 400/20

     =20m/s²
