Hi, i was wondering if anybody can help me with the following problem:(adsbygoogle = window.adsbygoogle || []).push({});

A plate drops onto a smooth floor and shatters into 3 pieces of equal mass. 2 of the pieces go off with equal speeds v at right angles to one another. How do I find the speed and direction of the third piece?

I know that the net momentum is conserved if the net external force acting on the system is zero, how can I apply this, any suggestions to which equations I can use?
