Does the question want you to calculate his accelerate on the ramp, or before it? Either way, you can't calculate tension right off the bat. The net force is going to equal the force of gravity on the 950kg mass. Divide that force by the system mass and you should get the acceleration before the...

Your mistake is in your calculation of normal force. Only m1 should factor into normal force. M2 experiences only gravity and tension :)

Okay, looking at my physics, it looks like the series expansion should look like \lim_{n \rightarrow \infty} (1/n) (cos \theta / n + cos 2 \theta / n +...+ cos \theta) . Does this help? Thanks, by the way, for the help and the patience. I was a little nervous about posting this because I know...

This actually came out of an analysis of trebuchets I'm doing for physics class. I'm trying to use this series sum (really the integral you've been describing, but I've been avoiding that because my calculus is weak) times a gravitational field strength and a length and mass of a pivoting arm to...

I probably did the notation wrong. I was aiming to describe the expansion I gave as a series sum but I wouldn't be close to stunned if I did it wrong (all of my series knowledge is self-taught and scantily so). What I was aiming at was, "I want to split an angle θ into n equal angles, then...

Homework Statement Find the limit of the series \lim_{n \rightarrow \infty} \sum_{i=1}^{n} cos (i \theta / n) , 0≤θ≤π/2 Homework Equations The Attempt at a Solution I know that the expansion looks like \cos \theta / n + cos 2 \theta / n + ... + cos \theta , but I couldn't begin...
