A basketball explodes into three separate pieces. Two pieces of equal mass shoot off at 20.3 m/s, one travelling to the south and one to the west, perpendicular to each other. The third piece has a mass 4 times the size of one of the other pieces. What is the speed of the third piece?

conservation of momentum in N/S and in E/W directions. Initial momentum is zero.
Could you actually show me how to do it?
