A spherical body of mass $\displaystyle 100$ g is dropped from a height of $\displaystyle 10$ m from the ground. After hitting the ground, the body rebounds to a height of $\displaystyle 5$ m. The impulse of force imparted by the ground to the body is given by: (given, $\displaystyle \mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^2$ )
Official answer
From NTA’s final answer key for this paper.
(1)
$\displaystyle 2.39 \mathrm{~kg} \mathrm{~ms}^{-1}$
