1. for those math geniuses, i have no idea where to even begin or start on this problem:

A 35kg box rests on the back of a truck. The coefficient of static friction b/w the box (mu s [mu static]) and the truck bed is 0.300.

a) when the truck accelerates forward, what happens to the box? (i'm guessing it stays where it is, doesn't move)
b) Find the max acceleration the truck can have before the box slides backward.

b is what i'm having trouble with, i know all the equations that i NEED to know for this question, it's just that i don't know where or how to even begin this question, it's the last question on this review sheet too (friction). HELP MUA PLEASE!!!!!!

3. damn the lounge is dead nowadays anyways, figured it out, i hope:

4. shit dude what kind of rocket science is that

5. by my calculations the jello dies out the orange within 3.26 seconds

nice, thanks for the answer Monkeee is the best

@mofos, don't take physics next year (11) it sux0rz lol, take earth science boring but easy.

7. @mofos, ever had mr.lee? fuckin hell, he's supposed to be the hardest teacher in our school. that last sentence sounds so wrong....

8. Dude what the hell are you studying?
why the fuck would you wanna know that?
and it's one of them stupid questions which is unrealistic cos it would also depend on what surface the truck back is and what kind of box and bottom the box is, also whether it's dry or wet and whther the wind is blowing etc, I hate stuff like that, it's so false

Sorry, too advanced for me, especially since I only been out of bed for 30 mins

9. Meh, I used to get kicked out of my Physics lessons so I wouldnt have been any use

10. I never done physics
