Question

A man strike a nail into a wooden block with an average force of 200n, if he continues to strike the nail with that force estimate how much heat energy will be generator by the time the nail penetrateds a depth of 0.05m

Answer 1

In the man applied 200 N along the entire 5 cm (0.05 m), the energy required will be

$$E=Fd=200\cdot0.05=10\text{ J}.$$
