An iron shot of mass 50g moving with a velocity of 150m/s, hits a fixed lead target of mass 2.5kg, and comes to rest by getting embedded in it. Assuming that 25% of the heat generated is lost to the surroundings, and that the remaining heat goes to increase the temperature of the iron shot as well as the lead target equally, find the rise in the temperature of the system. Specific heat capacities of iron and lead are 470 J//kg-^(@)C and 130 J//kg-^(@)C respectively.

1.	An iron shot of mass 50g moving with a velocity of 150m/s, hits a fixed lead target of mass 2.5kg, and comes to rest by getting embedded in it. Assuming that 25% of the heat generated is lost to the surroundings, and that the remaining heat goes to increase the temperature of the iron shot as well as the lead target equally, find the rise in the temperature of the system. Specific heat capacities of iron and lead are 470 J//kg-^(@)C and 130 J//kg-^(@)C respectively.
