Question

A lead bullet strikes against a steel plate with a velocity $200 \mathrm{~ms}^{-1}$. If the impact is perfectly inelastic and the hear produced is equal shared between the bullet and the target, than the rise is temperature of the bullet specific heat capacity of lead $=125 \mathrm{~J} \mathrm{~kg}^{-1} \mathrm{~K}^{-1}$ )\

$\mathrm{ms} \Delta \mathrm{T}=\frac{1}{2}\left(\frac{1}{2} \mathrm{mv}^{2}ight)$\ $\Delta \mathrm{T}=\frac{\mathrm{v}^{2}}{4 \mathrm{~s}}=\frac{(200)^{2}}{4 	imes 125}=\frac{4 	imes 10^{4}}{4 	imes 125}=80^{\circ} \mathrm{C}$\
