1. The problem statement, all variables and given/known data A 16 kg asteroid is traveling through space with velocity v = 180 m/s when it breaks up into three equal pieces. One piece is left at rest, and a second one continues with the same velocity. What was the energy of the explosion (in Joules)? 2. Relevant equations E=1/2mv^2 3. The attempt at a solution I tried using the kinetic energy equation cause it wants me to find energy, yet I'm pretty sure this is wrong. How do I go about solving this?
