By definition, the work is given by:

[tex] w = f * d
[/tex]

Where,

f: force acting in the direction of displacement

d: distance traveled

Substituting values we have:

[tex] w = 12 * 0.75
[/tex]

Therefore, the work done is given by:

[tex] w = 12 * 0.75

w = 9 J
[/tex]

Answer:

9 J of work is done on the 12.0n block by gravity
