A block with mass m1 on a plane inclined at angle ƒÑ to the horizontal is connected to a second hanging block with mass m2 by a cord passing over a small, frictionless pulley, as shown. The coefficient of static friction is Us ƒÝ
s and the coefficient of kinetic friction is UkƒÝ
k. Find the mass m2 for which block m1, moves up the plane at constant speed once it is set in motion.
Nice one UCT student ^^
