1.How much work is performed when a 25 N force was applied to pull the box at 20º from a horizontal over a distance of 8 m.

with solution.​


Sagot :

[tex]\tt{\huge{\blue{Explanation:}}}[/tex]

The work done by an object exerting a force F at an angle θ and at a distance d is given by

[tex]\boxed{W = Fd \: \cos \theta}[/tex]

where:

W = work

F = force

d = distance

θ = angle of the force with the horizontal

[tex]\tt{\huge{\red{Solution:}}}[/tex]

Solving for work

W = Fd cos θ

W = (25 N)(8 m)(cos 20°)

[tex]\boxed{W = \text{187.94 J}}[/tex]

Therefore, the work done is 187.94 J.
