AI Thread Summary
To find the slope of a staircase, measure the total rise and total run, then use the formula slope = rise/run. The user measured a total rise of 96 inches and a total run of 124 inches, calculating the slope as 24/31. Concerns were raised about this measurement not aligning with individual step heights, suggesting that measuring each step's width and height separately may yield different results. An error analysis is recommended if discrepancies arise, demonstrating a deeper understanding of the problem. Clarification on acronyms like "IMO" was also sought and provided.

Please help me w/ my Math project!

OK. Since no one was answering my last question, I have a new one. Its about my math project.
I have to find the slope of several staircases.
I decided to start with my own.
I feel really stupid saying this, but I have no idea how to go about finding the slope of my staircase. I can do it easily on paper, with graphs and stuff, but somehow I just can't figure this out. I feel really dumb asking a question like this on a board like this...but I'm desperate.
So far, i have measured the total run as 124" and total rise as 96". Then, I did the equation to find slope and I got 96/124 which I reduced to 24/31. Is this the slope? It didn't seem right at all to me, considering each step is only 7 inches high. I don't know if I'm completely off or did anything right...please help me! Walk me thru it!

IMO you won't get the same answer measuring the whole staircase and one step. Due to the fact that hte staircase is actually made in pieces.

measure the w & h of each step and sum the w's and sum the h's if you don't get the same answer as the measurement whole then do an "error" analysis and explain why you think this discrepancy resulted...this will show the teacher that you analysed the problem.
 
Ok...
what does IMO mean? Just wondering
 
OK thank you it worked.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
