Waves, graphs, & slinkies! :S

  1. Jan 18, 2007 #1
    Hello, I need help with some homework questions. I'd really appreciate it.
    I've tried some stuff, but I keep getting wrong answers, so here goes...



    2. If t3 = 1.70 s for slinky (b), find its frequency of oscillation.

    3. A mathematical formula for the motion of slinky (a) is y = A sin(kx−ωt). Find the value of ω if t2 = 9.00 s and x0 = 6.00 m.

    6. [1pt] A mathematical formula for the motion of slinky (b) is y = A sin(kx) sin(ωt+φ). If t2 = 0.80 s and x0 = 2.30 m, then find φ.

    7. [1pt] If t2 = 1 s and x0 = 4.00 m, then find the frequency of oscillation for slinky (a).

    You need to show some of your own work and thoughts in order for us to help you. What are the equations of SHM? How do they apply to these questions?
