Question

Find the magnitude and direction of

the net force being acted on the
free body diagram below.(look at the picture I provided)

Answer 1

Step-by-step explanation:

Pick your direction of the perpendicular forces.

Let down be negative and up be positive.

Remember that sum of all the forces is the net force,

So for the vertical forces, we have

`45 + ( - 45) = 0`

Next, pick your direction of the parallel forces.

Let right be positive and left be negative so we have

`15 + ( - 45) = - 30`

So our net force is 30 N to the left
