A lead bulletc just melts when stopped by an obstacle .bulle absorb 75%heat.find minimum speed of bullet.initial temperature is 27degree Celsius, specific heat capacity =0.126j/g/degreek Celsius and latent heat of fusion=25.2 /get.Here why do we multiply 10 power _3 to 1/2mv^2 while finding kinetic energy .the specific heat capacity is given in gram ,but in 1/2mv^2,we don’t need it.we want only mass
