An object explodes from rest into 3 pieces. The first piece launches at 4 m/s, 60 north of east. The second piece, which is twice as massive as the other two, launches at 3 m/s directly west. What is the direction of motion (in degrees from east) of the third piece that is equal in size to the first piece?
