Q126 / 160 · TS EAMCET 2025 (03 May Shift 1) · Physics

A body of mass 500 g is falling from rest from a height of 3.2 m from the ground. If the body reaches the ground with a velocity of $6 \mathrm{~ms}^{-1}$, then the energy lost by the body due to air resistance is $\left(\right.$ Acceleration due to gravity $\left.=10 \mathrm{~ms}^{-2}\right)$

A
14 J
Correct answer
B
7 J
C
21 J
D
28 J

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