Block 2 is at rest on the table with block 1 at rest on top of block 2. Friction does exist between block 2 and the table. Block 2 is attached to a string with negligible mass that passes over a pulley with negligible friction. The string is attached to a third box labeled box 3. (A) Part One: Draw and label the forces (not components) exerted on Block 2. Each force must be represented by a distinct arrow starting on, and pointing away from, a dot in the center. Draw the relative lengths of all arrows to reflect the relative magnitude of the forces. Part Two: Draw and label the forces (not components) exerted on Block 1. Each force must be represented by a distinct arrow starting on, and pointing away from, a dot in the center. Draw the relative lengths of all arrows to reflect the relative magnitude of the forces. (B) Block one is removed without disturbing block 2. Part One: Consider the scenario where the mass of block 2 is greater than the mass of block 3 and the table has negligible friction. Without using equations, make a claim about the motion of block 2 in terms of balanced or unbalanced forces. Part Two: Derive an equation for the acceleration of block 2 for any arbitrary values of m2 and mg. Express your answer in terms of m2, m3, and any physical constants as appropriate. (i.e. g for the acceleration due to gravity)
