1. The problem statement, all variables and given/known data The three blocks shown are relased at t=0 from the position shown in the figure. Assume that there is no friction between the table and M2, and that the two pulleys are massless and frictionless. The masses are: M1 = 1.0 kg, M2 = 7.0 kg, M3 = 3.0 kg. Calculate the speed of M2 at a time 1.45 s after the system is released from rest. (M1 is on left side of box, M2 is on the top of the box, M3 is on the right side of the box. Corners of box are pulleys.) 2. Relevant equations None. 3. The attempt at a solution I have ZERO clue.
