The 2kg block A and the 5kg block B are initially at rest on the inclined plane at 20 degrees. All surfaces in this system have a coefficient of static friction of 0.6 , and a coefficient of kinetic friction of 0.4. Calculate the size of the mass ‘m' so that block A slides relative to block B. block m is suspended over the wedge via pulley attached to B. A is at rest on top of block B
