AI Thread Summary
The discussion centers on understanding how to approach a physics problem related to work. Participants debate the correct application of the work formula, with some arguing that the initial equation presented is overly complicated for the problem at hand. There is confusion about whether to solve for force (F) or work (W), with emphasis on correctly using the definition of work. Clarification is sought on the relevance of the term "(0.5(M +m)v^2)" in the context of the problem. Ultimately, the focus remains on accurately applying physics principles to solve the problem effectively.

For the first part i got F=(0.5(M +m)v^2)/d

For the first question that is already too much. It's a trivial question about the definition of work. For the second part you should find the force acting on the plate, and again apply the definition of work.

What do you mean? I did use the definition of work to solve this

What do you need that "(0.5(M +m)v^2)" part for?

Are you not supposed to solve for F using the work formula?

You are supposed to find W, not F. And what does "(0.5(M +m)v^2)" have to do with that?
