Question

There are four forces acting on a car. The forces are:

a. 325N to the north
b. 175N to the south
c. 465N to the east
d. 255N to the west
Find the net force acting on the car.

Answer 1

| Fn | = 258 N

Step-by-step explanation:

Net Force

The net force vector is the sum of all the force vectors applied to a body.

There are four forces applied to a car:

325N to the north

175N to the south

465N to the east

255N to the west

To simplify the calculations, we find the net force by each axis separately, considering forces to the right and upward as positive.

Fx = 465 N - 255 N = 210 N

Fy = 325 N - 175 N = 150 N

The magnitude of the net force is:

`|Fn|=√(210^2+150^2)`

`|Fn|=√(44100+22500)`

`|Fn|=√(66600)`

| Fn | = 258 N
