Question

um
In the arrangement shown in the figure pulleys are small,
light and frictionless, threads are inextensible and mass of
blocks A, B and C is my = 5 kg, m2 = 4 kg and m3 = 2.5 kg
respectively and co-efficient of friction for both the planes is
u = 0.50. The acceleration of block A (in m/s?) when the
system is released from rest is 10k. Find k. (g = 10 m/
