22) For this question, we want to find the acceleration of the mass m[2]. The two masses are hung from opposite sides of the pulley. We are also told that we can ignore the friction and mass of the pulley.
We can start by using a free-body diagram for the two blocks.
Since m[2] and m[1] are connected by a string, both of the blocks should have the same acceleration. Knowing this, we can set up a system of two equations and solve for acceleration.
Answer: C
