Task data: V0 (vehicle speed before emergency braking) = 20 m / s; t (duration of emergency braking) = 5 s.
The braking distance of the vehicle under consideration during emergency braking is determined by the formula: S = V0 ^ 2 / (2 * a)) = V0 ^ 2 / (2 * (V0 / t)) = V0 * t / 2.
Calculation: S = 20 * 5/2 = 50 m.
Answer: The braking distance of the car in question during emergency braking was 50 meters.
