$[10]$ A spherical ball $($hollow sphere$)$ with mass $M=1\mathrm{.}05kg$ and radius $R=0\mathrm{.}01m$ rolls from initial velocity $v_o=0\frac{m}{s}$ towards a slop of height $h=1\mathrm{.}00m.$ The slop is located on top of a table $($see figure$).$ The ball has a horizontal $v_l$ at edge of the table top. The ball has projectile path from the edge of the table to the ground some distance $x.$ Height of the table is $H=2\mathrm{.}00m.$ Assume no air resistance.

$($a$)$ What is the speed $v_l$ of the ball before it goes off the edge of the table top?

$($b$)$ What is the $($translational$)$ speed $v_2$ of the ball just before landing to ground?
