| **Under the action of a force equal to 10n, the body moves with an acceleration of 2 m / s2, find the acceleration modulus of the body if its mass decreases by 1 kg and the force does not change.**

According to Newton’s second law:

F = m * a, where F is the force that acts on the body (F = 10 N), m is the body weight (kg), and is the acceleration of the body (a = 2 m / s²).

Let’s calculate the body weight:

m = F / a = 10/2 = 5 kg.

Acceleration of the body after a decrease in body weight by 1 kg and a constant acting force:

a1 = F / (m – 1) = 10 / (5 – 1) = 10/4 = 2.5 m / s².

Answer: The module of acceleration of the body will be equal to 2.5 m / s².
