Thanks guys! I'm glad to hear IB HL math is better than ap calculus from someone in it. Thanks for your perspective. I now don't feel to bad being enrolled in it. I just hope my math teacher makes smart cuts (only 3 kids should be in it at my school). I have been looking into competition math a...

Oh, and this is the IB program... Kind of regret doing it but we have no good ap classes where i live :(

Hey guys, I'm a 10th grader in High school right now. I am "ahead" in math right now, meaning I'll being finishing the BS high school calculus classes next year. Yet I'm still with other "gifted" kids who know jack all about maths :P My Senior year I plan on taking HL Math and tbh, I don't know...

I think your on the right track. Would'nt it just be from where you left off: Ffriction = ma Ff = ma UN = ma Umg = ma U = ma/mg U = a/g Also make sure to take the 10 degree into consideration and i think your good then.

a = -1.84 m/s^2 :P

I see what i did XD Lets see... (If this isn't right, ill shoot myself...JK)Sum of F = ma Fg - Ff = ma mg - UN = ma m1+m2gsin(16) - U X m1+m2cos(16)=m1+m2(a) a= m1+m2gsin(16) - Ux m1+m2cos(16)/ m1+m2 a= 5.26+4.8sin(16) - 0.204 X 5.26+2.8cos(16)/ 5.26+2.8 a=-1.84

I get 1.7 m/s^2. Tell me if that's right and i will explain. i think you went wrong on the friction bit. Friction = UN and force N=FG. You didn't add all your masses for some reason on the friction part.
