In the figure, the mass M?=4M? and the pulleys are smooth. At time t=0, the system is at rest with the positions of masses as shown in the figure. If the system is released, what is the maximum height reached by mass M?? (g=10m/s)

Answer:
  1. From the figure you can understand that the a1=a2/2.
  2. As from the constraint relation the block M2 will go twice as high as the block M1 will go downward.
  3. So when the block M1 will go down by 20 cm , the block M2 will go 40 cm upwards.
