A block of mass 15kg rests on a wedge (θ=26∘). The two objects move to the right in such a way that the block doesn't slide up or down the wedge. The coefficient of static friction between the block and the wedge is 0.35. What is the minimum acceleration of the two objects? What is the maximum acceleration of the two objects?

A wedge of mass M rests on a rough horizontal surface with
coefficient of friction µ. The face of the wedge is a smooth plane
inclined at an angle θ to the horizontal. A mass A hangs from a
light string which passes over a smooth peg at the upper end of the
wedge and attaches to a mass B which slides without friction on the
face of the wedge.

A block with mass M1 rests on a frictionless table. It is
connected by a massless string to a block with mass M2, which hangs
below the edge of the table. The system is released from rest at
time t = 0. Find the distance block M1 moves in time t. You may
assume that the string passes over a massless, frictionless pulley
at the edge of the table to assist your calculations.
