You have two issues here, first, Conservation of Momentum and second, Conservation of Energy.
Also any motion towards the left is arbitrarily negative and motion to the right, positive
Mg1= Mass Glider1
Vg1i= Initial Velocity Glider 1
Vg1f = Final Velocity Glider 1
Mg2= Mass Glider2
Vg2i= Initial Velocity Glider 2 (Note make Vg2i negative)
Vg2f = Final Velocity Glider 2
Conservation of Momentum
Mg1*Vg1i + Mg2*Vg2i= Mg1Vg1f +Mg2*Vg2f
Conservation of Energy
1/2*Mg1*(Vg1i)^2 + 1/2*Mg2*(Vg2i)^2= 1/2*Mg1(Vg1f )^2+1/2*Mg2*(Vg2f)^2
Plug all of number into the two equations above and you can solve for Vg1f and Vg2f.
(Note: Vg1f should be ~ - 3 and Vg2f ~ -2)
