The question I believe is asking just to determine the material based off the information given by using Newton's Second Law to find the coefficient of friction between the two materials. I have attempted this question did not get a reasonable result. Sorry if the post was not clear, hopefully...
I agree that it is a very open-ended question
Of course. This is a forces problem and I think one must find the coefficient of friction that exists between the two materials. Although it doesn't specify the direction the force is being applied or the the acceleration, I believe those may have...
