The mass of the blue (lower) puck in the figure below is 17.0 percent greater than the mass of the green (upper) one. Before colliding, the pucks approach each other with equal and opposite momenta, and the green puck has a initial speed of 10.9m/s. The angle 8 = 29.3º. Calculate the speed of the blue puck after the collision if half the kinetic energy is lost during the collision.
