Question

A horizontal force of 480 n is applied to a stationary wooden box in one direction and a 600 n horizontal force is applied in the opposite direction. What is the additional force is needed for the box to remain stationary

Answer 1

The additional force is
`F_3 = 120 \ N`

Step-by-step explanation:

From the question we are told that

The horizontal force in one direction is
`F_i = 480 \ N`

The horizontal force in the opposite direction is
`F_f = -600 \ N`

The negative sign shows that it is acting in the opposite direction

Generally for the box to remain stationary the net force on it must be equal to zero that is

`F_1 + F_2 +F_3 = 0`

Where
`F_3` is the additional force required

So

`F_3 = -F_1 - F_2`

substituting values

`F_3 = -480 - [-600]`

`F_3 = -480 + 600`

`F_3 = 120 \ N`
