Find the work done (in ft-lb) when a constant force F = 18 lb moves a chair from x = 0.6 to x = 1.4 ft.

The work done is 14.4 lb-ft

Explanation:

Given;

constant force, F = 18 lb

initial position of the chair, x₁ = 0.6 ft

final position of the block, x₂ = 1.4 ft

Work is said to be done, when an applied force moves an object through a distance.

W = F x d

where;

F is the applied force

d is the distance moved by the object

Distance moved by the object, d = x₂ - x₁

d = 1.4ft - 0.6 ft

d = 0.8 ft

W = F x d

W = 18 lb x 0.8 ft

W = 14.4 lb-ft

Therefore, the work done is 14.4 lb-ft

answer( sicar );

explanation:

to push or pull an object in a certain direction is known as force. a force in moving an object from one place to another.

force depends on the mass of an object. so, more is the mass of an object more will be the force required to move the object.

thus, we can conclude that the use of force to move an object is push or pull.
