Question

The 12.0n block descends 0.75m. at constant speed. how much work is done on the 12.0n block by gravity?

Answer 1

By definition, the work is given by:

`image`

Where,

f: force acting in the direction of displacement

d: distance traveled

Substituting values we have:

`image`

Therefore, the work done is given by:

`image`

Answer:

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