Hi there I am having a lot of trouble trying to figure out this homework problem and I really need help. This problem is dealing with wave motion and I do not know how to set up the formula to get the correct answer. Please help me and show some steps how to approach this problem.
Here is the problem:
A transverse sinusodial wave on a string has a period T=43.0ms and travels in the negative x direction with a speed of 30.0 m/s. At t=0, a particle on the string at x=0 has a transverse position of 2.00 cm and is traveling downward with a speed of 3.50 m/s.
a) what is the amplitude of the wave? in meter
b) what is the phase constant? in rad
c) what is the maximum transverse speed of the string? in m/s
d) write the wave function for the wave.
y(x,t)=

Use the first equation as the model.
Use that, and post your thinking. I will be happy to critique your thinking. Let me know if you know simple calculus (ie dy/dx)
