1. The problem statement, all variables and given/known data An explosion breaks an object into two pieces, one of which has 1.5 times the mass of the other. If 7400 J were released in the explosion, how much kinetic energy did each piece acquire? 2. Relevant equations Momentum? Kinetic Energy? 3. The attempt at a solution I used all types of formulas having to do with energies and momentum and nothing gave me an answer.
