Hi everyone, i recently got this problem from my college professor and I am either incredibly rusty or just don't know how to do this. I've tried to set up some sort of equation using f(x) but i just can't make anything fit or account for everything. any help would be appreciated. the...

yah! it is. how did u get that.

i thought i gave the restrictions? it was from 48-60. that is why i was saying i get undefined from the chain rule. sorry for the confusion

well the thing is this is a problem in our calculus book in the section under logarithmic and exponential integration. which is wierd. there is nothing else to the problem except what i have given here. the book asks for the answer to that probability equation and wants it as a percentage. while...

can anyone figure this out? i keep getting undefined somewhere but my teacher says there is a correct answer. heres the problem. .0065 times the integral of e to the (-.0139(t-48)squared) power. i can't find the integral cause i get undefined when the chain rule is used to chain out the...

thanks a bunch! helps tremendously!

see the thing that is hard for me is finding those things to make up k using only what i have for my experiment, which is like a stop watch and ruler stick thing and a video camera maybe. my teacher was saying how i need to find an easier way to find terminal velocity without doing too complex...

so let me make sure i have this down correctly. so to find terminal velocity i take the mass of the object, multiply that by the force of gravity and divide that whole quantity by the surface area of the parachute? thanks for the help by the way.

okay so i posted earlier (while back) regarding terminal velocity. I have a parachute experiment set up, but i cannot find a way to calculate terminal velocity. does anyone out there have a formula i can use to find terminal velocity if all i got is a good old fashioned pencil, paper and...

Well i understand to use the stopwatch method but let me know if I am setting this up right. My teacher refuses to help us. I got the parachute things set up. And a set vertical height i can drop from. I am going to use a video camera to help play out the falling motion too. To calculate...

This is my first time posting here but i need some serious help. I'm in the process of doing a physics project right now, and I decided to relate the surface area of an object to its terminal velocity. I know how I am going to set up this experiment using coffee filters and string and a set...
