The mass of the blue puck shown below is 35.0% greater than the mass of the green one.Before colliding, the pucks approach each other with momenta ofequal magnitudes and opposite directions, and the green puck has aninitial speed of 8.0 m/s. Find thespeeds of the pucks after the collision if half the kinetic energyof the system becomes internal energy during the collision.
vgreen = m/s
vblue = m/s
