Question

The pulley shown in the diagram is frictionless A cat of mass 1 kg moves up on the
massless string so as to just lift a block of mass 2 kg. After some time, the cat stops moving
w.r.t. the string. The magnitude of the change in the cat's acceleration is

Answer 1

Answer:

initial upward acceleration of cat = g

final acceleration = (2-1) g/ 2+1= g/3 (upward)

change in cats acceleration = g - g/3 = 3g-g/3

=3g/3
