The bob of a pendulum was released from a horizontal position. The length of the pendulum is $\displaystyle 10$ m . If it dissipates $\displaystyle 10 \%$ of its initial energy against air resistance, the speed with which the bob arrives at the lowest point is:
[Use, $\displaystyle \mathrm{g}: 10 \mathrm{~ms}^{-2}$ ]
Official answer
From NTA’s final answer key for this paper.
(4)
$\displaystyle 6 \sqrt{5} m s^{-1}$
