    [2 problems] Transverse Waves, Superpostion & Reflection

    So am I to assume that there is nothing wrong with Q1 and that WebAssign is being a PoS? And thanks to everyone that helped. I really appreciate it.

    [2 problems] Transverse Waves, Superpostion & Reflection

    @PiTHON: I don't know the correct answer for time1. Using this webassign thing, and there's no answer key. If an answer's incorrect, it'll tell you, but won't tell you the correct answer. & thank you for the explanation about the pi's. I understand now. @hikaru: Q1: The wave travels to the...

    [2 problems] Transverse Waves, Superpostion & Reflection

    Question 1 1. Homework Statement The drawing shows a snapshot of a transverse wave traveling along a string at 9.6 m/s. The equation for the wave is y(x, t) = A cos(ωt + kx). At what times could this snapshot have been taken? (Give the three smallest nonnegative possibilities.)The Attempt at a...

    Vectors (?), Change in Velocity, Average Accel.

    OH WOW. It worked. Just needed to ignore the middle velocity they gave. Thank you very much! For part (b), the direction of the acceleration should be the same as the direction of the velocity, right? Or should I find the X&Y components of the acceleration and take the arctan of that? Wanna...

    Vectors (?), Change in Velocity, Average Accel.

    Nice to meet you all. While this may be my first post here, I will be here quite often for the next year because I'll be taking physics. Homework Statement John drives 15 km directly west from Orion to Chester at a speed of 86 km/h, then directly south for 7.0 km to Seiling at a speed of...
