A small ball of mass m starts at a point A with speed $\displaystyle v_{\mathrm{o}}$ and moves along a frictionless track AB as shown. The track BC has coefficient of friction $\displaystyle \mu$. The ball comes to stop at C after travelling a distance L which is :
Official answer
(2)
$\displaystyle \frac{h}{\mu}+\frac{v_o^2}{2 \mu g}$
