Homework Help: Momentum in explosions

  1. Dec 3, 2003 #1
    Homer the human powder keg, initially at rest, suddenly explodes into 3 pieces each with = mass. One piece moves east at 30 m/s and a second piece moves at 30 m/s south east

    a) calculate the speed of the 3rd piece and direction

    Problem i'm having is I can't find the angles because they are not given. With at least one given angle i could solve the problem. Is there a way to find an angle?

    The angles are given with the directions. East and South East are 45º apart. You can also find a compass bearing of the thrid piece.
