Question

We are studying elastic collisions. There is this system of equations problem where we are solving for the first and second final velocities. Help!

equations: m1v1,i+m2v2i = m1v1f+m2v2f
0.5m1v1i^2+0.5m2v2i^2 = 0.5m1v1f^2 + 0.5m1v1f^2

Givens: m1= 2kg
m2=3kg
v1,i= 4m/s
v2,i=-5m/s
unknown:
v1,f= ?
v2,f=?
Please help!
