Two boxes with masses m¡ = 8.5 kg and m2 = 3.0 kg are connected by an ideal rope over a pulley with mass M = 1.2 kg, as shown. There is friction between m2 and the ramp. The system is released from rest, causing m to drop by a distance h = 2.9 m, at which point its speed is 4.65 m/s. What is the coefficient of kinetic friction between m, and the ramp?
