i used the conservation of momentum equation and conservation of energy equation
got m1.v1i + m2.v2i = m1.v1f + m2.v2f
and 1/2 m1 . v1i^2 + 1/2m2 . v2i^2 = 1/2 m1.v1f^2+ 1/2 m2.v2f^2
i know it's a simutaneous equation but i don't know how to solve it!
1.1 + 0 = 0.11 x + 0.3y
5.5 + 0 = 0.55x^2 + .15y^2
(this is for the elastic one)
