A 11.9 g iron bullet with a speed of 3.00 multiplied by 102 m/s and a temperature of 20.0°C is stopped in a 0.400 kg block of wood, also at 20.0°C.
(a) At first all of the bullet's kinetic energy goes into the internal energy of the bullet. Calculate the temperature increase of the bullet.
°C
(b) After a short time the bullet and the block come to the same temperature T. Calculate T, assuming no heat is lost to the environment.
