A mass m1 = 1 kg on a horizontal table is pulled by a string looped over a massless frictionless pulley and attached to another hanging mass m2. The coefficient of kinetic friction between the table and mass m1 is 0.5 and the coefficient of static friction is 0.6.
a) What is the minimum mass m2 that will start both masses moving?
b) What is the acceleration of the system with this minimum mass?
