It is claimed that if a lead bullet goes fast enough, it can melt completely when it comes to a halt suddenly, and all its kinetic energy is converted into heat via friction. find the minimum speed of a lead bullet (initial temperature = 27.4 °c) for such an event to happen.

354.72 m/s

Explanation:

= mass of lead bullet

= specific heat of lead = 128 J/(kg °C)

= Latent heat of fusion of lead = 24500 J/kg

= initial temperature = 27.4 °C

= final temperature = melting point of lead =  327.5 °C

= Speed of lead bullet

Using conservation of energy

Kinetic energy of bullet = Heat required for change of temperature + Heat of melting

b) returns freshwater to the earth.
