The force of 10n acts on a body of mass 2kg for a distance of 1m . the kinetic energy acquired by the body is

Explanation:

Begin by finding the acceleration with Newton's second law: F = ma.

10 = 2 * a => a = 5.0 m/s^2

Then use the "shortcut" velocity equation = + 2 a * x

v = = 3.16

Then use the equation for kinetic energy: k =

k =

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.
