A700- kg vehicle is traveling at the speed of 6m/s how much kinetic energy does it have

Kinetic energy = 1/2 x mass x velocity²

Kinetic energy = 1/2 x 700 x 6²

Kinetic energy = 12600 J

The kinetic energy will be 12600 J

As we know that

Kinetic energy = 1/2 (m) (v)²

By putting the values

Kinetic energy = 1/2 x 700 x 6²

We get

Kinetic energy = 12600 J

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
