How much work is needed to move an object 20 meters with 40 newtons of force? a) 800 J
b) 850 N
c) 875 W
d) 825 m

a) 800 J

Explanation:

Work is said to be done when a force induces movement over a distance in an object. The amount of work done (W) is calculated by multiplying the force by the distance traveled.

That is;

W = F × d

Where;

W = work done (J or N/m)

F = force (N)

d = distance (m)

In the information given in this question, F = 40N, d = 20m

Hence,

Work done = 40N × 20m

Work done = 800N/m or 800 J

tbh i don't know the answer for this question
