Two masses are connected over a pulley by a massless string, as shown at right. One has mass mi = 10 kg and the other has mass m2. The horizontal m1 surface is rough, with a coefficient of static friction of 0.35 and a coefficient of kinetic friction of 0.15. The system is released at time t = 0. 3) If mass m2 = 3 kg, what friction force acts on mass mi after the system is released? m2 4. If mass m2= 5 kg , what friction force acts on m1 after the system is released
