| **A small body weighing 0.1 kg rests on a smooth horizontal surface. Two horizontally directed forces simultaneously begin to act on it, the moduli of which are 0.3 N and 0.4 N. What is the maximum acceleration in modulus that this body can acquire?**

The body will acquire the maximum acceleration if the forces act on it in one direction. Let’s write Newton’s second law for this case:

ma = F1 + F2, where

m = 0.1 kg is the mass of the body in question,

F1 = 0.3 N – the first force acting on the body,

F2 = 0.4 N – the second force acting on the body,

a =? is the acceleration to be found.

We get the formula for calculating the acceleration:

a = (F1 + F2) / m

Substitute the given values:

a = (0.3 H + 0.4 H) / 0.1 kg = 7 m / s ^ 2
