**drwls**, Wednesday, March 17, 2010 at 1:11pmUse conservation of momentum in two perpendicular directions. Because of the equal speeds, the final direction will bisect the angle between the incoming vectors. You can write a single momentum equation along that direction, and solve for final speed Vfinal

2*72 * cos 65*7.00 m/s= 2*72 * Vfinal

Vfinal = 7.0 cos 65
