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