This deposit is called gunshot residue and consists of particles of the propellant or explosive primer.
Experimentation has shown that the period of time that is person will test possible for gunshot residue is 5.27 days.
Explanation:
When spring is used to shoot an arrow, the Elastic Potential Energy is converted into Kinetic Energy.
The efficiency of Spring Toy = 69%
<u>According to Conservation of Energy</u> :
P. E. = K. E.
NOW,
69% of P. E. = m * v^2 / 2
