Question

A man strikes a nail into a wooden block with an average force of 200N. Estimate how much heat energy is generated when the nail penetrates 0.05m.

A) 10 J
B) 20 J
C) 30 J
D) 40 J

Answer 1

The estimated heat energy generated is calculated using the work done by the force acting over a distance, yielding 10 Joules (Option A) as the correct answer.

Step-by-step explanation:

The student's question asks to estimate the amount of heat energy generated when a nail is struck into a wooden block with an average force of 200N over a distance of 0.05m. To calculate the work done, which in this context is converted into heat energy, the formula Work = Force × Distance is used. Therefore, the work done by the man on the nail is 200N × 0.05m = 10J.

So, the correct answer is A) 10 J. This is the estimated amount of heat energy generated due to the force applied over a distance when the nail penetrates the wooden block.
