Thankfully, I won't be doing another physics course after this term. I usually read ahead throughout the semester, but really got off track within the past few weeks. Luckily, I currently have an A, so I can afford to do not-so-well on the final. ha.

Okay, its a little more clear now. I'm going to go study until my eyes water and/or begin to blur. Any study tips to offer?

So how will I know when its centripetal and when it isn't? I'm so confused. :(

Okay. I've been defeated. I still can't get acceleration. I used a = 2.05/1.24 = 1.65 and that's not correct.

Okay, great. I looked at that website, and it eliminates my next question (I was going to ask how to calculate acceleration, but its all there) so you just saved me (and yourself) from more pain. haha. Thank you (twice). :)

I'm just trying to get through it now...try to pass the CAPA part of the course even if I can't pass the exam. haha. It says in my notes that the equation I derived above was for tangential v...so are tangential and linear the same thing?

Wellll...technically...he doesn't go anywhere, as he ends up in the same place ;).

So that's the equation for linear velocity? I'm confused. I just grabbed that out of my notes.

Homework Statement A rotating merry-go-round makes one complete revolution in 3.80 s. What is the linear speed of a child seated 1.24 m from the center? Homework Equations vt = wr w = 2(pi)/T Vt = 2(pi)r/T The Attempt at a Solution I know that the further you are from the center...

hahah now now, be nice.

oooh. hahah sorry. its exam week, I'm feeling a bit slow. so your formulas are actually x + y = 3.58 and then 5x = 6y. I understand, thank you :).

Sorry...I'm not following. Where did the 5 come from?

Homework Statement To determine the location of the center of mass of a car, the car is driven over a scale. When the front wheels are over the scale, the weight recorded by the scale is 5.05 x 103 N. When the rear wheels are over the scale, the scale reads 6.20 x 103 N. The distance between...

See, that's the part that confuses me, the drawing of the arrows on the diagram. How do you know what direction N is pointing in? Whats mg? Etc. I'm really not understanding this entire topic.

I have N=f/mu but I don't know F or N. Hah. I'm usually not this terrible at physics, I promise.
