Answer:
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
