A transverse wave on a string is described by the equation

Question

Solve the following problem given below:

Problem: A transverse wave on a string is described by the equation y(x, t) = (2.12 cm) sin[(101 rad/s)t + (14 rad/s)x].

Part I: Find the maximum transverse speed of a point on the string?

m/s

Part II: What is the maximum transverse acceleration of a point on the string?

m/s²

Part III: How fast does the wave move along the string?

m/s

Part IV: Why is your answer to (c) different from the answer to (a)?

I need tutor help to solve the above problem.
