The two blocks in the figureoscillate on a frictionless surface with a period of 1.7s . The upper block just begins to slip when the amplitude is increased to 38cm .
What is the coefficient of static friction between the two blocks?

The figure, which we cannot see, must contain additional information on masses or spring constant. You have not provided enough information to answer the question.

Is one block on top of the other? If so, maximum acceleration will require the maximum force, which will occur at maximum spring displacement. Set that force equal to Us*M*g and solve for Us, the static friction coefficient

The answer is 16

there is no masses or spring constants and yes one block is on top of the other, thank you for the help!
