The Work–Kinetic Energy Theorem

[TONI2012]

I would appreciate help to solve the problem proposed in Figure 6-4 by PA Tipler 5th Ed ("What did your professor exert force if the sled starts with a speed of 2 m / s ... "). Thanks

We don't own your textbook.

You'll have to post the full problem, preferably with a drawing, picture or scan of the diagram included.

You will also have to tell us how you've approached the problem so far.

 

[TONI2012]

Attached simplified scheme and a resolution scheme.

In Tipler, gives values ​​for d, v0 and vf and gives the solution (138N). I can understand that the value of M is the previous problem in the book.

But neither the value nor the H m are supplied. With the scheme that I propose, I think they are necessary.

I appreciate any help.

Thank you.

I see nothing attached.

OK. (I happen to have that book, so I know what you are referring to.)

But neither the value nor the H m are supplied.

I don't understand this sentence. What values are not supplied?

With the scheme that I propose, I think they are necessary.

Show your proposed solution. (No values beyond what was given are needed.)

For the benefit of others, please post a scan of the textbook problem. Or at least a better statement of the problem.

Sorry!

Are you sure you are looking at the correct figure, which is figure 6-4? Your attachment looks closer to figure 6-5, which is a different problem.

You're right. Thanks
