During a July 4th firecracker party, a pop bottle rocket laying still on the ground explodes, sending fragments everywhere. If the momentum of the pop bottle rocket (ignore friction and air resistancel) initially at rest is conserved during an explosion, what can be said about the kinetic energy of various fragments after the collision? OA The kinetic energy of the various parts of the system are necessarily conserved. OB The sum of all the kinetic energy of the various pieces is equal to what it was originally. OC The total kinetic energy afterwards is greater that what it was initially OD. The total KE afterwards is less that what it was initially
