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 34cm .

What is the coefficient of static friction between the two blocks?

It is not clear what the figure shows.

To determine the coefficient of static friction between the two blocks, we need to analyze the forces acting on the upper block.

First, we need to understand the conditions under which the upper block just begins to slip. When the block just begins to slip, the static friction force between the two blocks reaches its maximum value.

The static friction force (F_static) can be defined as:

F_static = coefficient of static friction (μ_s) * normal force (N)

In this case, the normal force is equal to the weight of the upper block, which can be calculated as:

N = mass of upper block (m) * acceleration due to gravity (g)

Now, we need to find the weight of the upper block. The weight can be calculated using the formula:

Weight = mass * acceleration due to gravity

To calculate the weight of the upper block, we need to know its mass. Unfortunately, the mass of the upper block is not given in the question. Without the mass, we cannot proceed with calculating the weight, normal force, and static friction force. Therefore, we cannot determine the coefficient of static friction between the two blocks based on the given information.

In order to find the coefficient of static friction, we would need additional information such as the masses of the blocks.
