| **Find the modulus of acceleration of a body weighing 2.5 kg under the action of four forces applied to it, if: F1 = F4 = 20H, F2 = 16H, F3 = 17H**

We will use Newton’s second law to solve this problem, if all forces are codirectional, then their resultant is F = 40 + 16 + 17 = 56 + 17 = 73N

a = F / m = 73 / 2.5 = 73 * 2/5 = 146/5 = 29.2m / s ^ 2
