An object explodes and breaks into 2 pieces. Piece 1 has twice the mass of piece 2.
A) Which piece has more momentum?
B) Which piece has more kinetic energy? Answer the question using all necessary equations and calculations to show how you arrive at your conclusions. Just saying A is greater than B is not enough.
