    The basic equation of motion for harmonic motion is:



    You have been given the value for . Now take the derivative of this to find the particle's velocity:



    You have been given the max value of its velocity, so you can now determine the value for A.

    The equation for acceleration is the derivative of the velocity equation - you can do the math and determine its maximum value. Post back with what you get and we'll check it for you.
