Homework Statement
An artillery shell of mass 10 kg is launched due east at 3,000 ft/sec at an angle of 30 degrees above the horizontal. It explodes 5 seconds later, and splits into 2 pieces - one of mass m1 3 kg and the other m2 of mass 7 kg. Neglect air resistance. The 3 kg piece lands 4 seconds after the explosion at a point 20,000 ft. east and 3,000 ft north of the launch point. When and where does the second piece land?
