Q. The three blocks shown are released at t=0 from the position. Assume that there is no friction between the table and M2, and that the two pulleys are massless and frictionless. The masses are: M1 = 3.0 kg, M2 = 9.0 kg, M3 = 5.0 kg.
Determine the speed of M2 at a time 1.85 s after the system is free from rest.
