3. Two blocks with unequal masses, M and m (M> m), are connected by a light, very long string passing over a pulley of negligible mass, as shown in the figure, and then released. Friction is negligible. a. If one of your classmates calculated that, once released, the acceleration of the blocks would be g, '6 without doing any calculations, say whether or not this could be a reasonable value for the acceleration. Draw and label a free body diagram (FBD) for each block. (Be sure your drawings show clearly any information you know about the directions and relative magnitudes of the forces.) Rank the relative magnitudes of all forces in your FBDS. (I'm looking for a single ranking that includes every different force drawn and labeled in both FBDS, separated by <, >, or =.) heavy block: b. light block: relative sizes of all forces in FBDS: C. Use the FBDS from the previous part, and Newton's 2nd Law, to derive an expression (in terms of M, m and g) for the acceleration of the blocks once they're released. bonus) If the blocks start a distance y above the ground, use kinematics to find whať's the maximum height above the ground that the small block reaches before falling back and hanging above the ground? (Assume that pulley is high enough that the small block doesn't touch it. Attach your own paper with work.)
