Specific heat capacity

A $4.0\,\text{g}$ aluminium pellet at $22.0^{\circ}\text{C}$ falls $40.0\,\text{m}$ onto a hard surface and does not bounce. Assume $15\%$ of the loss in gravitational potential energy increases the internal energy of the pellet. Given the specific heat capacity of aluminium is $900\,\text{J kg}^{-1}\text{K}^{-1}$, calculate the rise in temperature of the pellet.
