Answer :
Answer: 9 m
Explanation:
Work is said to be done when an unbalanced force causes displacement of the body.
Force is the product of mass (m) and acceleration (a).
Work = Force × Displacement
⇒W = F.s = ma.s
It is given that mass of the dresser is, m = 250 kg
work done, W = 126 J
Force acting on the dresser, F = 14 N
we need to find displacement, s
⇒126 J = 14 N × s
⇒ s = 126 J/ 14 N = 9 m
Hence, Laurie is able to move the dresser to about 9 m.

Answer:
9 m
Explanation:
When an object moves or displaces along the direction of the applied force application of force, it is said that work is done.
We know the formula of work:
Work = force x displacement
where force = mass x acceleration
So this formula can be further broken down to :
Work = mass x acceleration x d
Putting in the given values to get:
126 = 14 x d
d = 126/14
d = 9 m
Therefore, the dresser was moved by 9m.
