Question

a farmer lift a sac of weight of 100kg to a height of 2 m. find work done. with explanation​

Answer 1

Answer:

w=mgh=100×9.8×2=1960j

This work is done against gravitational field (g=9.8m/s²)

Answer 2

Answer:

M = 100 kg

h = 2 m

Work done against gravitational force,

W = mgh

    = 100 x 9.8 x 2

    = 196 J
