Forces of 3 N and 4 N are applied to the body, directed perpendicular to each other, as shown in the figure. In this case, the body moves with an acceleration of 5 m / s ^ 2. What is the mass of this body?
We add the perpendicular vectors according to the parallelogram rule: F = √ (3 ^ 2 + 4 ^ 2) = 5H, F = ma => m = F / a = 5H / 5m / s ^ 2 = 1 kg.
