A lead bullet weighing `18.0g` and travelling at `500 m//s` is embedded in a wooden block of `1.0kg`. If both the bullet and the block were initially at `25.0^(@)C`, what is the final temperature of the block containing bullet? Assume no temperature loss to the surrounding. (Heat capacity of wood `= 0.5 kcal kg^(-1) K^(-1)`, heat capacity of lead `= 0.030 kcal kg^(-1) K^(-1))`
