# Under the action of a force equal to 10n, the body moves with an acceleration of 2 m / s2

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. One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
