specific heat; calormetry (no clue)

[heelp]

the 1.2okg of a hammer has a speed of 6.5m/s just before it strikes a nail and is brought to rest. Estimate the temperature rise of a 14g iron nail generated by such hammer blows done in quick succession. Aaaume the nail absorbs all the energy.

Have you given any thought on how you approach this problem?
What is the energy of the hammer just before the collision?
