A 3.0-kilogram steel ball whose initial velocity is 10∠20 meters per second and a 5.0-kilogram block of putty whose initial velocity is 30∠60° meters per second slide on a frictionless surface, as shown. The objects collide and the ball imbeds itself in the putty. Find the velocity of the combined mass immediately after impact.
