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).
