yes, I understand finding the 2 components of gravity in both the horizontal and vertical, but I do not have a mass to multiply the acceleration due to gravity by. mg means mass*9.8 :P

Bump, its due tomorrow!

Ummm...what? I don't understand how to deduce the weight/mass of the skier still.

Yes we know that. We actually have that one done. Problem 2 is the skier on the slope.

1. http://sites.google.com/site/startngovr/ 2. \SigmaF = \Sigmam*a F_{k}=\mu*N X_{f} = 1/2 at^{2} V_{f} = at For problem 1 we think the answers are as followed: \mu_{s} does not = 0.2 a = 5.32m/s^{2} For problem 2 we have no idea what to do. We have too many...

I believe I stated "if for example the interval 0 to 3 was negative" not that it WAS indeed negative. It was 11pm and I didn't feel like doing any work at the moment. Basically though, I split the two up and add them together to find the total. It's like a displacement problem?

So (I haven't checked), if the interval 0 to 3 is negative and 3 to 8 is positive. I would say the answer is the negative interval plus the positive one? I need a little further explanation I think. We just started this in class and I had to miss half of the lecture.

Homework Statement \int^{8}_{0}\left|x^{2} - 6x + 3\right|dx This is for a single variable AP Calculus AB class in which we are solving using substitution method. 2. The attempt at a solution I attempted it by just ignoring the abs value bars thinking that anything I am finding out...
