Question

A small ball of mass $m$ is thrown upward with velocity $u$ from the ground. The ball experiences a resistive force $m k v^2$, where $v$ is its speed. The maximum height attained by the ball is

Select the correct option:

$\frac{1}{2 \mathrm{k}} \tan ^{-1} \frac{\mathrm{ku}^2}{\mathrm{~g}}$

$\frac{1}{\mathrm{k}} \ln \left(1+\frac{\mathrm{ku}^2}{2 \mathrm{~g}}\right)$

$\frac{1}{2 k} \ln \left(1+\frac{k u^2}{g}\right)$

$\frac{1}{\mathrm{k}} \tan ^{-1} \frac{\mathrm{ku}^2}{2 \mathrm{~g}}$

✓ Correct! Well done.
