Homework Statement
A mass "m1" moves along the x-axis with velocity of magnitude v0 on a frictionless table. It strikes another mass m2 which is initially at rest. The mass m1 goes off along the y-axis. If half the original kinetic energy is lost in the collision, with what speed and at what angle does m2 leave the point of collision?
Homework Equations
1/2KE(initial) = KE(final)
(1/2)Pix=Pfx
(1/2)Piy=Pfy
The Attempt at a Solution
Pix=vom1
Pfx=u2m2cosθ
Piy=0
Pfy=u1m1 - u2m2sinθ
I think these are the initial and final components of momentum, but I don't know how to find θ and u2 in terms of known variables.
