$1$ points

$1-$D Motion: A ball bearing with mass $98\mathrm{.}9$ g has an initial velocity $6\mathrm{.}71\frac{m}{s}($to the right$)$ heading toward a second stationary ball bearing of mass, $104$ g $.$ Calcualte the final velocity of the first ball bearing after the elastic collision in mks units. Type the units right after your numerical answer.
