d = .5(vo + v)t I think I found it, but is this equation only applicable because the acceleration is constant? Maybe I'm not clear on why the first equation to find the distance wasn't relevant.

I don't understand why. I've got all my variables accounted for in the equations I have, don't I? Am I not just going about the wrong way interpreting the problem?

Well I think I'm a little closer. vf = vi + at is what I feel like I'm going to need, but I'm just not sure how to integrate acceleration here.

Homework Statement A hockey puck with mass 0.160 kg is at rest at the origin (x = 0) on the horizontal, frictionless surface of the rink. At time t = 0 a player applies a force of 0.250 N to the puck, parallel to the x-axis; he continues to apply this force until t = 2.00 s. (a) What are...

Thank you so much! :D

Having some trouble with this exercise; help appreciated! :] Homework Statement Homework Equations Fx + Fy = F Pythagorean Theorem The Attempt at a Solution basically I used the trigonometric identities to conclude that the necessary force was 69.28N and the Y...

Are you saying that, in addition to the observer finding that the subject on the event horizon appears to move slowly, the subject on the event horizon will also appear to be redder? If that's true, will the observer appear to be blue from the subject's point of view, since photons will be...

I've got a pretty simple question, and it may sound dumb, but I'm going to ask it anyway: First, I'll preface by saying that from what I understand (and please verify or correct me), planetary orbit in a star system decays over time a la net force. I also have come to understand that the...
