The momentum of the bullet is only 3,000 of the same unit. but that 3,000 is then concentrated into a single point, whereas the momentum of the car is spread out over a much larger area upon impact.
I just hope that certain US citizens don't interpret this as an argument in favour of bigger guns - I can imagine a few being disappointed to learn their projectiles carry less kinetic energy than a moving SUV.
Another story from the US today, a teenager how was charged and expelled over a minor prank
According to the Miami New Times, "[A] police report ... indicates Wilmot mixed toilet bowl cleaner and aluminum foil -- a combination that has inspired hundreds of YouTube videos and generally produces a fairly unimpressive explosion."
The experiment reportedly created a small explosion that caused the bottle's top to pop off and produced smoke. Although no one was hurt and no property was damaged, Wilmot was charged with “possession/discharge of a weapon on school property and discharging a destructive device,” according to WTSP. Both charges are felonies.
