Question

How much work does it take to raise a `3 kg` weight `1 m`?

Answer 1

29.43 J

Explanation:

Now based on the formula,

Work done= force × displacement in the force's direction

Here, the force you apply is equal to the weight of the object you're carrying which is:

W= mg = 3× 9.81= 29.43 N

Now the displacement of the object is 1 m. So the work done here is:

W= f.s = 29.43 × 1= 29.43 J
