Homework Statement Here's a graph of displacement it wants me to make: http://s15.postimg.org/7v1x5najv/graph.png. I tried that graph in the picture as the answer but it didn't accept it. There are no numbers or specifics for Figure 1 they give you, so I'm confused on what to do. Very strange...

Yup! You're right, how foolish of me :D

So this looks really easy, but I can't get the right answer. It asks you to find the minimum acceleration from the graph: http://s22.postimg.org/f5dutd5ap/pic.png. This is of course the point where the slope is the smallest, and this is from t = 3-4 s or t = 4-5 s, depending on whether you want...

Yeah, that's all a bit over my head. I had pre-calc/trig 5 years ago and AP Calculus 3 years ago. Thank you for explaining it, though, you are very knowledgeable on this subject!

We haven't been taught how to do anything with trigonometric things yet but are rather expected to from previous coursework. I guess I don't understand what you would do with trigonometry in calculating this or how sine factors into this since you're given the value and the uncertainty estimate...

Parts C and D: http://s7.postimg.org/pnq5gry63/image.png Part D of this problem is just like Part C above it. The only difference is the presence of "sin," but that doesn't affect the calculation of percent uncertainty at all. Chapter 1 of my Physics book (Physics: Principles with Applications...
