Figure shows two blocks, each of mass m. Thesystem is released from rest. If accelerations ofblocks A and B at any instant (not initially) are aand a2, respectively, then niuฝ่าmntm(b) a)a, cos θ(c) a a2 of these

Answer»

From the string constant acceleration of string should be a1

so acceleration of block b along the string is a2cos∅ , that should be equal to a1

=> a1 = a2cos∅.
