Block 1 is resting on the floor with block 2 at rest on top of it. Block 3, at rest on a smooth table with negligible friction, is attached to block 2 by a string that passes over a pulley, as shown above. The string and pulley have negligible mass.
Block 1 is removed without disturbing block 2.
i. Consider the scenario where the mass m3 of block 3 is greater than the mass m2 of block 2. Without using equations, make a claim about the motion of block 3 in terms of balanced or unbalanced forces.
ii. Derive an equation for the acceleration of block 3 for any arbitrary values of m3 and m2. Express your answer in terms of m3, m2, and physical constants as appropriate.
(c) Describe in what way your answer to part (b)(ii) is or is not consistent with your claim in part (b)(i).
