Question:

A small ball of mass $m$ starts at a point $A$ with speed $v_{o}$ and moves along a frictionless track $\mathrm{AB}$ as shown. The track $\mathrm{BC}$ has coefficient of friction $\mu$. The ball comes to stop at $\mathrm{C}$ after travelling a distance $\mathrm{L}$ which is:

1. $\frac{2 h}{\mu}+\frac{v_{0}^{2}}{2 \mu g}$

2. $\frac{\mathrm{h}}{\mu}+\frac{\mathrm{v}_{\mathrm{o}}^{2}}{2 \mu \mathrm{g}}$

3. $\frac{\mathrm{h}}{2 \mu}+\frac{\mathrm{v}_{\mathrm{o}}^{2}}{\mu \mathrm{g}}$

4. $\frac{h}{2 \mu}+\frac{v_{o}^{2}}{2 \mu g}$
