Vedclass · Answer

$\begin{array}{l}
Initial\,speed\,at\,{m{point}}\,{m{A,u}}\,{m{ = }}\,{{m{v}}_0}\
speed\,at\,{m{point}}\,B,v = ?\
\,\,\,\,\,\,\,\,\,\,\,\,{v^2} - {u^2} = 2gh\
\,\,\,\,\,\,\,\,\,\,\,\,{v^2} = v_0^2 + 2gh\
Let\,ball\,travels\,{m{distance}}\,'S'\,before\
{m{coming}}\,to\,rest
\end{array}$

$\begin{array}{l}
S = \frac{{{v^2}}}{{2\mu g}} = \frac{{v_0^2 + 2gh}}{{2\mu g}}\
 = \frac{{v_0^2}}{{2\mu g}} + \frac{{2gh}}{{2\mu g}} = \frac{h}{\mu } + \frac{{v_0^2}}{{2\mu g}}
\end{array}$

A small ball of mass $m$ starts at a point $A$ with speed $v_0$ and moves along a frictionless track $AB$ as shown. The track $BC$ has coefficient of friction $\mu $. The ball comes to stop at $C$ after travelling a distance $L$ which is
