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:

$w = f * d$

Where,

f: force acting in the direction of displacement

d: distance traveled

Substituting values we have:

$w = 12 * 0.75$

Therefore, the work done is given by:

$w = 12 * 0.75 w = 9 J$

Answer:

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