Question
The weight of the block is .08kg and the angle of the ramp is about 19 degrees.
Problem 2: By lifting slowly on an inclined plane, a block at rest can be set into motion. Determine experimentally the angle in which a block breaks free. This angle is related to the static coefficient of friction Hs. Repeat the experiment several times until results are consistent. Measure the height and the base of the right triangle that is formed to determine using tan=ad.

Using Newton's Laws in the x and y directions produces the olowinagsquatonetident fietion.tis In the x direction the acceleration is considered to be zero just when the puck breaks free, thus a = 0·In general, f ,N, W= mg then from the equation in x:Explanation / Answer
It's very easy. I assume that the ramp angle which you have given in the question is found out by using
tan(theta) = opposite / adjacent
As the angle of ramp is found out to be 19 degrees, We can easily calculate us (coefficient of friction)
us = sin(theta) / cos(theta) = tan(theta)
us = tan(19)
us = 0.3443
As you might have observed, coefficient of friction does not depend on mass or weight.
