Kinetic energy of system becomes internal energy-collision

Reference no: EM13545126

The mass of the blue puck shown below is 25.0% greater than the mass of the green puck. Before colliding, the pucks approach each other with momenta of equal magnitudes and opposite directions, and the green puck has an initial speed of 7.0 m/s. Find the speeds the pucks have after the collision if half the kinetic energy of the system becomes internal energy during the collision.
