The 7 kg box-A released from rest and moved along the frictionless curved path and then moved along the rough linear path from C to D. When the box-A hits the box-B having a mass of 3 kg, plastic impact occurs. After the impact, determine the total distance that the box-B travels in meters. Circular path is frictionless. Horizontal surface has a coefficient of kinetic friction μk = 0.25. Ignore the dimension of the boxes. (g = 10 m/s2) Note: Please answer with 3 digits after the comma!
