# Determine the centripetal acceleration of a car moving at a speed of 72 km / h along a curve with a radius of 100 m / s

January 28, 2021 | education

| To determine the desired centripetal acceleration of a given car, we will use the formula: an = V ^ 2 / R, where V is the speed of the rounding (V = 72 km / h or 20 m / s); R – radius of curvature (R = 100 m).

Let’s perform the calculation: an = 20 ^ 2/100 = 4 m / s2.

Answer: A given car was moving along the curve with a centripetal acceleration of 4 m / s2.
