The car, the mass of which is equal to 2 tons, and the thrust force of the engine is equal to – 4 kN

The car, the mass of which is equal to 2 tons, and the thrust force of the engine is equal to – 4 kN, starts to move. How far will the car go in 10 seconds?

1) Let’s calculate the acceleration with which the car is moving (Newton’s second law).

F = m * a, where F is the thrust force of the engine (F = 4 kN or 4000 N), m is the mass of the vehicle (m = 2 t or 2000 kg).

a = F / m = 4000/2000 = 2 m / s2.

2) Calculate the distance traveled by the car.

S = V0 * t + a * t ^ 2/2, where V0 is the initial speed (since the car started off, V0 = 0 m / s), t is the time of movement (t = 10 s).

S = a * t ^ 2/2 = 2 * 10 ^ 2/2 = 100 m.

Answer: The car will cover 100 meters in 10 seconds.
