Two ways to change the energy of a system; First law of thermodynamics; Specific heat
A lead bullet of mass m traveling at vi penetrates a wooden block and stops. (a) Represent the process with a bar chart. What system did you choose? (b) Assuming that 50% of the initial kinetic energy of the bullet is converted into thermal energy in the bullet, write an expression that would allow you to determine the block’s temperature increase. (c) List all of the physics ideas that you used to solve this problem.
