2) m, m. 2, Two masses are attached by a string over a pulley as shown above. The hanging mass is 4.00 kg and the mass on the ramp is 5.00 kg. The angle of inclination of the ramp is 30.0° and the coefficient of kinetic friction between the mass and ramp is 0.250. The masses are released; what is the acceleration of the hanging mass? What is the minimum coefficient of static friction such that the masses do not move when they are released?
