Source:

A small block moving with initial speed

v_\text{0}

moves smoothly onto a sloped big block of mass

M

. After the small block reaches the height

h

on the slope, it slides down. Find the height

h

h=\frac{v_\text{0}^2}{2g}

h=\frac{1}{g}\frac{Mv_\text{0}^2}{m+M}

h=\frac{1}{2g}\frac{Mv_\text{0}^2}{m+M}

h=\frac{1}{2g}\frac{mv_\text{0}^2}{m+M}

h=\frac{v_\text{0}^2}{g}
