A lead bullet a 15°C is brought to rest on hitting a target. If the bullet thereby just melts completely, find the velocity of bullet just before impact. Assume that all the heat produced on impact remains in bullet. Sp. ht. of lead = 0.03 cals/g/°C, melting point of lead = 325°C, L of fusion of lead = 5 cal/g, J= 4.2 x 107 ergs/cal. %3D
