To calculate the value of the traction force acting on the presented car, we use the formula: Ftyag = ma * a = ma * 2S / t ^ 2.
Variables: ma – vehicle weight (ma = 2 t = 2 * 10 ^ 3 kg); S – distance traveled (S = 100 m); t is the duration of the vehicle acceleration (t = 10 s).
Calculation: Ftyag = ma * 2S / t ^ 2 = 2 * 10 ^ 3 * 2 * 100/10 ^ 2 = 4 * 10 ^ 3 N.
Answer: The traction force acting on the presented vehicle is 4 kN.
