The car moves along a curvature of the road with a radius of 20 cm with a centrifugal acceleration of 5 m / s2. Determine vehicle speed.

1) Let’s convert units to SI: distance 20cm = 0.2m.

2) Centripetal acceleration is calculated by the formula: a = v2 / R.

3) Let us express the speed from the acceleration formula: v = √ a * R;

4) We make calculations: v = √5m / s2 * 0.2m = √1m2 / s2 = 1m / s.

Answer: v = 1m / s.
