true or false: 1. during an explosion, the total kinetic energy is always conserved 2. An impulse always goes in the same direction as the applied force. 3. during an explosion of an object the sum of the momentum of all fragments is equal to the momentum of the object before the explosion 4. The momentum of a system is always conserved even if an external force acts on the system. 5. Momentum is a vector quantity during a perfectly inelastic collision between two masses the two masses rebound after the collision.
