Question

what is the net force on the object represented by the free - body diagram below? f_left = 25 n, f_right = 40 n. clear all 25 n 65 n 40 n 15 n

Explanation:

Step1: Define net - force formula

The net force $F_{net}$ on an object is the vector sum of all forces acting on it. For forces acting along a straight - line, if we take the right - direction as positive and the left - direction as negative, and we have two forces $F_1$ and $F_2$ acting on the object, then $F_{net}=F_2 + (-F_1)$.

Step2: Identify the forces

Here, $F_1 = 25N$ (acting to the left, so it is negative in our sign convention) and $F_2 = 40N$ (acting to the right, so it is positive).

Step3: Calculate the net force

$F_{net}=40N+( - 25N)=40N - 25N = 15N$.

Answer:

15 N
