Answer:

Step-by-step explanation:

The formula for calculating work done is expressed as

Work done = force x distance

Since the object is being moved horizontally, the horizontal component of the force will be required. Thus,

Work = Fdcosθ

where

θ is the angle made with the horizontal

From the information given,

θ = 80

F = 800

d = 30

Work done = 800 x 30Cos80

Work done = 4167.556J
