Question

A stone thrown upwards reaches a maximum height of 3 m calculate the work done by the force of gravity during the vertical displacement if the weight of the stone is 1.96 newtons in brain

Answer 1

Distance (S)
$= 3m$

Weight (F)
$= 1.96N$

Therefore,

Work done
$= F×S$
$= 1.96 \times 3$
$= 5.88J$
