Answer:
Explanation:
Given
mass of bullet [tex]m=5\ gm[/tex]
speed of bullet [tex]v=355\ m/s[/tex]
bullet is stopped by building and heat produced is shared between building and bullet
Kinetic Energy of bullet is converted into Thermal energy
Kinetic Energy of bullet [tex]K=\frac{1}{2}mv^2[/tex]
[tex]K=0.5\times 5\times 10^{-3}\times (355)^2[/tex]
[tex]K=315.06\ J[/tex]
So 315.06 J of Energy is converted in to thermal energy
