Question

an object at rest explodes into three pieces of equal mass. one moves east at 20 m/s a second moves southeast at 30 m/s what is the velocity of the third piece??
the sum of the momentums equal zero. Break up the SE into S, E vectors, then the third will be the negative of the sum of the others.
