A lead bullet strikes against a steel plate with a velocity 200m/s. If the impact is perfectly inelastic and the heat produced is equally shared between the bullet and the target, then the rise in temperature (in ∘C) of the bullet is (specific heat capacity of lead s=125J/kgK)

Solution
We know that: Q=msΔθ
Given: s=125J/kgK,v=200m/s
Half of kinetic energy is getting converted into heat to increase temperature of lead bullet,
