Solve the all parts of following question given below:
Question: A transverse sinusoidal wave on a string has a period T = 25.0 ms 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 4.50 m/s.
Part I: What is the amplitude of the wave?
... m
Part II: What is the phase constant?
... rad
Part III: What is the maximum transverse speed of the string?
...m/s
I need expert help to solve the above question.
