10 seconds after the start of movement, the car developed a speed of 20 m / s.

10 seconds after the start of movement, the car developed a speed of 20 m / s. find the force reported by the acceleration if the mass of the car is 20 tons.

The force imparting acceleration to the body is calculated by the formula F = m * a, that is, this force is equal to the product of the mass of the car and its acceleration.

We find the acceleration by the formula a = (V – V0) / t, where the initial speed V0 = 0, t is the time during which the car develops the speed V.

Then, a = 20 (m / s) / 10 (s) = 2 (m / s2).

We translate the units of measurement: 20 tons = 20,000 kg.

Therefore, the force imparting acceleration to the bodies is F = 20,000 (kg) * 2 (m / s2) = 40,000 N.

Answer: force F is equal to 40,000 N.
