Homework Statement
A block of mass M is pulled at constant speed with force F a distance d across a surface. Using the energy principle, what can you say about the change in thermal energy of the block?

Homework Equations
The Attempt at a Solution
I believe the change in thermal energy is 0 (b) because it is being pulled at a constant speed so nothing is actually changing. Is my logic correct to say it is b?
I only have one attempt left
