To find out the required power of the presented car, consider the formula: Na = Ft * V, where Ft is the acting traction force (Ft = 2000 N = 2 * 10 ^ 3 N); V is the constant speed of the presented car (V = 20 m / s).

Let’s perform the calculation: Na = Ft * V = 2 * 10 ^ 3 * 20 = 4 * 10 ^ 4 W.

Answer: The required power of the presented car is 40 kW.
