a 357-magnum bullet has kinetic energy of 540 ft lb at 50 yards from the pistol. If it strikes and comes to a rest inside a 1.0 kg block of wood (with a specific heat capacity of 1700 J/kg K), by how much would the block's temperature change? The bullet is lead and weighs 158 grains (1.0 grain is equivalent to 0.0648 g).
