A lead bullet of mass 3.43 g and temperature 28.6C traveling at an unknown speed gets embedded in a block of ice of temperature 00C. Calculate the initial speed of the bullet if 0.500 g of ice melts. Assume that the entire kinetic energy of the bullet is converted into heat, that is transferred to the ice. Also, do not forget that the bullet cools down from 28.6C to 0C. Express your answer in m/s

A firearms company is testing a new model of rifle by firing a 7.50-g lead bullet into a block of wood having a mass of 17.5 kg. The bullet embeds into the block and the collision generates heat. As a consequence, the temperature rises by 0.040°C, as measured with a high-precision thermometer. Assuming that all the kinetic energy of the bullet goes into heating the system, what is the bullet’s speed when it enters the block? The initial temperatures of...
