Homework Statement Hmm, well, this isn't an actual homework question. It's more of a general one, but it does apply to homework. What I want to know is, for momentum, how do you know when to use sine and cosine for vectors? Likeeee, let me show you an example of what I mean: This is a...

Oh wow, I can't believe I didn't see it before. Thanks so much for your help, it makes sense now...

I said that because b and c are in m/s^2 and m/s^3, not meters...unless that doesn't matter? =\ But I see what you mean, it saying distance...

Homework Statement A car is stopped at a traffic light. It then travels along a straight road so that its distance from the light is given by x(t) = bt^2 - ct^3, where b = 2.30 m/s^2 and c = 0.120 m/s^3. (a) Find the average velocity of the car for the time interval t=0 to t=10 s (b)...

Yes, sorry, there is a picture that goes with this: That's it right there. Thanks for any help :)

This is for a first year university question in Physics (Mechanics). 1. Write each vector in terms of the unit vectors i(hat) and j(hat). Use the unit vectors to express the vector C\rightarrow where C\rightarrow = 3.00A\rightarrow - 4.00B\rightarrow. Find the magnitude and direction of...
