Question

Calculate the net force when the forces

25 N [N], 15 N [S], 35 N [E] and 25 N [W]
acts on the same object. Draw a diagram
for this situation. [4]

Answer 1

`10 √(2)`

Explanation:

the net force can be found by finding the horizontal and vertical forces.

the vertical force is 25-15=10 north.

the horizontal force is 35-25=10 east.

the resultant force from these two can be found through Pythagoras theorem

10^2+10^2=200

sqrt(200)=10sqrt(2) is our net force, direction northeast.
