A crate is being pulled to the right a distance of 10 m, with applied force 120 N at an angle of 60 degrees to the ground , if the friction on the box is 10 N, calculate the net work done on the crate ?

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.
