A body with a mass of m = 400 g moves under the action of a force F = 10 H. What acceleration does the body receive?

The acceleration of a body can be determined by the formula a = F / m, where a is the acceleration of the body, F is the applied force, m is the mass of the given body.
Using the data from the condition of the given problem, we obtain that a = 10 N / 400 g = 10 N / 0.4 kg = 25 m / s ^ 2 = 90 km / min ^ 2.
Answer: a = 90 km / min ^ 2.
