Desperate! (basic physics help)

**Mafoo** · 02-09-2011, 02:02 PM

can someone show me how to solve these? my professor is not all that helpful and im struggling badly.

any help is really appreciated, i havent done much physics in my life

HTAM · 02-09-2011, 02:06 PM

These. Hmm. Everything you need to know about 'These' can be found here.

These | Define These at Dictionary.com

Also, I think this is an english question?

HTAM · 02-09-2011, 02:11 PM

In all seriousness try Newton's second law.

This is a popular physics question you can find the answer to if you look carefully.

**Mafoo** · 02-09-2011, 02:11 PM

thanks for your non help. i was referring to the GIANT screen shots i uploaded der

i know its newtons laws, i can do these easily on flat surfaces, i dont know how to correct for the angle/ the angle on the normal force/ angle on the weight of the body

**Mafoo** · 02-09-2011, 02:16 PM

ok i got the second one its 60 degrees, thank you yahoo answers

im gonna fail this classs

ok and i got the other one too. i did accel of gravity times sine of the incline times the mass.

thanks for not just giving me the answer htam i actually understand what i was fucking up now

kitch · 02-09-2011, 02:22 PM

the answer to number 1 is f=all the merlot in a wino's dreams

**Mafoo** · 02-09-2011, 02:25 PM

i got the same answer

Waves · 02-09-2011, 02:38 PM

i cant help you but i wish i could. im no good at math and science, just not wired for it

**Mafoo** · 02-09-2011, 02:46 PM

im a bio major and i struggle with math to no end.

i shoulda picked art or something

fenderbender · 02-09-2011, 02:47 PM

ugh my physics is a million times more basic then this and it's still a pain in the ass :/...

yeah so instead of being a scientist you can be a burger flipper!

(at least theres not much thought involved :P)

fenderbender · 02-09-2011, 02:51 PM

what area in bio you focusing on mafoo?

Qui-Bong Jinn · 02-09-2011, 02:56 PM

I don't even know what those symbols mean, I salute you Mafoo.

Kompressor · 02-09-2011, 03:10 PM

Had I stumbled upon this earlier I would have helped.

1. 3*3800* Tan(18) = 1234.69

[Edit: Oops meant Cos(18) = 10842.04]

2. .5 = Cos(60)

**Mafoo** · 02-09-2011, 03:13 PM

just general bio. i had hopes of going into research of some sort, but im not sure i can handle grad school at this point so we will see what happens.

alot of science is overcoming the WTF reflex and letting your mind relax so that it can think correctly, the symbols dont really add to the complexity of the material, if anything they make the work easier

**AlteredStateGrl** · 02-09-2011, 03:15 PM

i don't know if this will be helpful, but PLEASE check it out and keep it handy for future use...the site is fucking awesome and has thousands of tuts.

fenderbender · 02-09-2011, 03:25 PM

thats a cool site.

Ive seen the online material of the bigger universities but that shits still too advanced for me.
This site looks spot on lol.

thanks asg

**Mafoo** · 02-09-2011, 03:50 PM

thanks ASG, im sure that will come in handy at some point

another cool site if anyone likes physics widgets

phet.colorado.edu

**Mafoo** · 02-19-2011, 03:22 PM

got another one im stuck on.. im guessing its also quite simple but im struggling and ive been doing problems for 3 hours so my minds feeling strained

my_scatterheart · 02-19-2011, 03:41 PM

You can do grad school Mafoo, I have faith. It's just about really getting into the learning, instead of it just being some passive thing you do four days a week, or whatever.
