1. The problem statement, all variables and given/known data A body, initially at rest, explodes into two pieces of mass 2M and 3M respectively, having a total kinetic energy E. What is the kinetic energy of the piece of mass 2M after the explosion? 2. Relevant equations 0.5mv²=K.E 3. The attempt at a solution The velocity of the 2 pieces of objects is different,how do i calculate? Can anyone guide me on how to start? 0.5(2m)(v_1)² + 0.5(3m)(v_2)²=E How do i proceed? Thanks for reading,thinking,replying.
