A lead bullet penetrates into a solid object and melts. Assuming that 50% of its kinetic energy was used to heat it, calculate the initial speed of the bullet. The initial temperature of the bullet is 27C and its melting point is 327C. Latent heat of fusion of lead = 25 x 10 J kg and specific heat capacity of lead = 125 J kgK.
