Question

How much work is done when a 4.0-newton box is carried horizontally a distance of 2.0 meters at a constant velocity?

Answer 1

the answer is 0.0J. that's what I found out after i turned it in then corrected it

Answer 2

Answer: Work done by the box will be 8 Joules.

Explanation:

Work done by a substance is the product of the force applied on it and the displacement of a substance.

Mathematically,

$W=F.s$

Where,

W = work done = ? J

F = Force applied = 4 N

s = displacement = 2 m

Putting values in above equation, we get:

$W=4N\times 2m=8Nm=8J$

Hence, work done by the box will be 8 Joules.
