# Conservation of momentum in two dimensions

The picture (attached) shows two pucks about to collide and one of them after the collision, what is the velocity (Magnitude and Direction) of the .4 kg puck after the collision? (The point of the question is to use the conservation of momentum equations)

Two blobs of clay have the initial velocities shown below. The velocities are at right angles to each other. If they collide and stick together, what will be the magnitude and direction of their velocity after the collision?
