Physics

To determine the work done, we need to calculate the component of the force that is in the direction of the displacement. The formula for work is: W = Fdcos(θ)

 

where:

W is the work done,

F is the force applied,

d is the distance over which the force is applied,

θ is the angle between the force and the direction of displacement.

 

Given:

F = 90N

d = 8m

θ = 45°

 

Plugging in the values, we get:

W = Fd cos(θ)

W = 90 × 8 × cos(45°)

W = 720 × cos(45°)
