Law Enforcement - Explosions

How do law enforcement officers determine the strength of an explosion based on the movement of objects around the point of origin? Scholars inspect the relative mass and velocities of two cars before and after an explosion. They perform simple calculations of momentum using the given mass and velocity.  The lesson fits as one part in a larger series on Momentum and Collisions.
