Homework Statement
Two 0.25 kg blocks are connected by a thread that passes over a frictionless pulley. The thread has no mass, and no friction. The two blocks are in balance. If a third block that weighs 0.20 kg is put on one of the blocks, then what is the acceleration of the 0.20 kg block?
Homework Equations
The Attempt at a Solution
I was thinking that since the 0.20 kg block just disrupts the equilibrium of the 0.25 kg blocks, then wouldn't the 0.20kg block just accelerate as if it were just dropped, at 9.8 m/s^2?? That seems like too obvious of an answer though...
