Explanation:Work done by force applied against gravity for one lift will be
W = Fs = mgh = 10 x 9.8 x 0.5 = 49J
So work done for 1000 lifts = 49 x 1000 = 49000 J

Work done against gravity:
Work done (W) = mass(m) × gravity (g) ×height(h)
W=mgh = 10×9.8×0.5 = 49J
1000 times the work is done. So total work done= W× 1000= 49×1000= 49000J.
