Physics

To calculate the work done by the net force, we first need to find the net force acting on the object along the horizontal direction, since the displacement is along the horizontal.

 

Resolve the forces

is acting horizontally to the right.

 

is acting at an angle of above the horizontal, so we need to find the horizontal component of :

Thus, the horizontal component of is .
