A large block is being pushed against a smaller block such
that the smaller block remains elevated while being pushed.
The mass of the smaller block is m = 0.30 kg. It is found
through repeated experimentation that the blocks need to
have a minimum acceleration of a = 13 m/s² in order for the
smaller block to remain elevated and not slide down. What is
the coefficient of static friction μ, between the two blocks?
