Question 7

A worker pushes a heavy crate across a horizontal floor at a constant speed. The worker applies a constant force 'F' over a distance 'd'. Which of the following statements accurately describes the energy transformations and work done in this scenario?

Accepted Answer

B. The work done by the worker is Fd, and the work done by friction converts mechanical energy into heat. — Since the crate moves at a constant speed, its kinetic energy remains unchanged, meaning the net work done on it is zero according to the Work-Energy Theorem. The worker does positive work (Fd), and this work is entirely balanced by the negative work done by friction (-Fd), which converts the mechanical energy into thermal energy (heat). Therefore, option B is correct. Option A is incorrect because net work is zero and kinetic energy is constant. Option C is incorrect because mechanical energy is not conserved due to the presence of friction. Option D is incorrect because the work done is diss

Answer

A. The net work done on the crate is Fd, and its kinetic energy increases.

Answer

C. The total mechanical energy of the crate remains constant, as it moves at a constant speed.

Answer

D. The work done by the worker is entirely converted into the kinetic energy of the crate.
