A spherical body of mass $100 \mathrm{g}$ is dropped from a height of $10 \mathrm{m}$ from the ground. After hitting the ground, the body rebounds to a height of $5 \mathrm{m}$. The impulse of force imparted by the ground to the body is given by: (given $g=9.8 \mathrm{m} {\mathrm{s}}^{-2}$)

• A

  $4.32 \mathrm{kg} \mathrm{m} {\mathrm{s}}^{-1}$
• B

  $43.2 \mathrm{kg} \mathrm{m} {\mathrm{s}}^{-1}$
• C

  $23.9 \mathrm{kg} \mathrm{m} {\mathrm{s}}^{-1}$
• Correct answer
  D

  $2.39 \mathrm{kg} \mathrm{m} {\mathrm{s}}^{-1}$

Hence, the correct answer is option: 'D'.
