Solution

Find the height:
Given data:
Work done, $W = 100 J$
Mass, $m = 200 g$
$m = 0.2 k g$ $(∵ 1 k g = 100 g)$
Acceleration due to gravity, $g = 9.8 m s^{- 2}$
The work done formula is
$W o r k d o n e = F o r c e (F) \times d i s p l a c e m e n t (s)$
Where, $F = m g$ and $s = h$
$W = m \times g \times h$
Substitute the values
$100 = 0.2 \times 9.8 \times h$
$h = \frac{100}{1.96}$
$h = 51.02 m$
The engine supply with an energy supply $100 J$ can lift the weight $200 g$ to a height of $51.02 m$
