The car covered 20 meters in 2 seconds. The engine thrust was 20kN. find her power

To find out the engine power of the specified car, consider the formula: N = F * V = F * S / t.

Data: F – engine thrust force (F = 20 kN = 2 * 10 ^ 4 N); S – distance traveled (S = 20 m); t – elapsed time (t = 2 s).

Let’s perform the calculation: N = F * S / t = 2 * 10 ^ 4 * 20/2 = 20 * 10 ^ 4 W = 200 kW.

Answer: The engine of the specified vehicle must have a power of 200 kW.
