In a collision , the laws of physics mean that even smaller items that
are loose in the vehicle will turn into heavy missiles that can cause
serious injury. Items in the vehicle pick up kinetic energy which
varies with the vehic le and the weight of the item . Vehicle speed is
the most significant factor.
For example , in a frontal collision at a speed of 30 mph (48 km /h) ,
the forces acting on a 10-lb (4 .5 kg) object are about
20 times the
normal weight of the i tem . This means that the weight of the item
would suddenly be the equivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an i tem of tha t weight flying free ly _,,,
