In an elastic collision- using momentum conservation and equation for coefficient of restitution- we get-v1-m1-x2212-m2m1-m2u1-2m2m1-m2u2

In an elastic collision, using momentum conservation and equation for coefficient of restitution, we get,v1=m1−m2m1+m2u1+2m2m1+m2u2

In an elastic collision, using momentum conservation and equation for coefficient of restitution, we get,
$v_{1} = \frac{m_{1} - m_{2}}{m_{1} + m_{2}} u_{1} + \frac{2 m_{2}}{m_{1} + m_{2}} u_{2}$
