Homework Statement After reviewing a quiz I had in Statics, I realized I did not understand why a certain force was considered in the moments equation. If a force goes directly through the point of the moment, it is not considered when solving for a force using moments. The question is asking...

Thank you so much for the explanation!

We were discussing using L'Hopital's rule for indeterminate forms to evaluate the sequence below. I just don't understand how that limit is 1∞. I guess I'm still fuzzy on how to figure out limits?

I'm trying to understand why the ## \lim_{n \rightarrow \infty} ( \displaystyle \frac {n+1}{n-1} ) ## equals the indeterminate form 1∞? I ask because we have started going over sequences and it was used as an example. I understand how to go from here- taking the ln of both sides and using...

I think so, although I'm not sure what the s and u are for.

Homework Statement [/B] You throw a small rock straight up from the edge of a highway bridge that crosses a river. The rock passes you on its way down, 5.00 s after it was thrown. What is the speed of the rock just before it reaches the water 21.0 m below the point where the rock left your...

Thank you! Will do!

Honestly, I'm pretty new to all this so I'm not familiar with how to use LaTeX properly. In the problem description I was quoting the description verbatim from my assignment. Thank you for the help! I don't know how I made those silly algebra errors...

Ok. I'm getting tired so maybe I've made a silly algebra error somewhere, but I'm getting crazy numbers. I must not be doing an algebra manipulation correctly, but I can't seem to figure out where I've gone wrong in my simplification of the square root. \

If it helps, this is the answer I found on Chegg.com. However, I don't understand how they got from the 1st step to the 2nd step. I've tried it a few different ways and have yet to end up with what they have. I also don't fully trust sites like that as they are not always correct.

I'm sorry, I was doing a problem previous to this one where it was dx/dy. I meant to use dy/dx throughout the problem.

Homework Statement Find the area of the surface generated by revolving the curve y=√x+1, 1≤ x ≤5, about the x-axis. I'm stuck trying to figure out how I can use substitution...if I am even able. I was trying to rewrite 1 as 4(x+1)/4(x+1) but still can't seem to get the right terms to cancel...

Thank you! I rechecked my math, and somehow I must not have entered it into my calculator correctly. This may be a silly question, but how would I know it's supposed to be at least 333? Is it because 333 was the largest squared number and it was added to the other number?

Homework Statement [/B] A plane leaves the airport in Galisteo and flies 180 km at 67.0 degrees east of north; then it changes direction to fly 255 km at 49.0 degrees south of east, after which it makes an immediate emergency landing in a pasture. When the airport sends out a rescue crew, how...
