Answer:
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
