"Pounding an nail into wood makes the nail warmer. Consider a 5-g steel nail 6 cm long, and a hammer that exerts an average force of 600 N on it when driving the nail into a piece of wood. About how much hotter will the nail become? (The specific heat capacity of steel is 450 J/kgC.)"(adsbygoogle = window.adsbygoogle || []).push({});

Here's my work:

Given: m = 0.005 kg, d = 0.06 m, F = 600 N, c = 450 J/kgoC

Unknown: ΔT

Equation: W = Fd, Q = mcΔT

Substitution: W = 600 N * 0.06 W = 30 J

30 J = 0.005 kg * 450 J/kgoC * ΔT

Solution: ΔT = 16 oC

Is this correct?
