Extracted text: The system consisting of objects with mass ma 1 (kg), mg 2,kg) and massless and frictionless pulleys and ropes is as shown in the figure. At t 0, the force F = 101 (N) starts pulling the middle pulley upwards. Find the velocity of object A in (m/s) when the object B loses contact with the ground? g = 10 (m/s?) F = 10t A) 5 В) 40 C) 10 D) 20 E) 90
