Hi there I am having so much problems trying to solve this physic problem and I really need help. Please give me a big hint on how to find the amplitude of this problem because i tried using everything i know and i cannot figure it out. This homework problem deals with wave motion.
Here is the problem:
A transverse sinusoidal 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 transverse position of 2.00 cm and is traveling with a speed of 3.50 m/s.
a) what is the amplitude of the wave? in meters

I sincerely hope you mean physics, not physic. They are entirely different!

you know the y is 2 at t=0, x=0
Yes the equation I gave you yesterday to figure out amplitude from all the given information.
