Oh. You're right, they wouldn't want to exclude visitors based on mass!
After reviewing friction a bit more, I have:
Friction opposes gravity here, so Friction = mg
Friction also = m(a sub c)u
So I can substitute one of these friction equations into the other-- divide mass out of both sides...
Okay... then I guess I'm stuck as to where to go from there. I don't know how'd I'd go about finding normal force without being given mass. I admit that my understanding of friction is not what it needs to be; I can visualize what you're saying, but I can't quite figure out how to relate it back...
Homework Statement
In an old-fashioned amusement park ride, passengers stand inside a 3.0-m-tall, 5.0-m-diameter hollow steel cylinder with their backs against the wall. The cylinder begins to rotate about a vertical axis. Then the floor on which the passengers are standing suddenly drops away...
Okay, thank you. I was just a bit nervous about leaving anything out that could potentially be relevant because my instructor is known for being an extremely tough grader. I just wanted to be sure that there wasn't something important that I hadn't thought of. Thanks again!
That's basically what I thought... Still, do you think it would have been pertinent to the report to write equations that show how the driving process works? That is, for instance, to write out the solvation of phenacetin in the solvent mixture similar to that of NaCl in water
(NaCl + H2O-->...
I just submitted a lab report for a TLC experiment, but I just realized that I completely forgot to include the "reactions" section. It's too late to save that grade, but for future reference, how would one go about writing out a chemical equation for a TLC experiment? I had always understood...
