Question

Two students push a heavy crate across the floor. John pushes with a force of 185 N due east and Joan pushes with a force of 165 N at 30∘north of east. What is the resultant horizontal force on the crate?

Answer 1

Answer:

327.894 N

Explanation:

We have given two forces Jhon pushes with a force of 185 N in east direction and Joan pushes with a force of 165 N at 30° north of east which is clearly shown in figure

We fave to find the total horizontal force

So total horizontal force will be $F_X=185+165cos30^{\circ}$ =327.894 N ( total horizontal force will be sum of force in the east direction and horizontal component of the force in north- east direction)
