A hand holds two blocks. The mass of the bottom block is 15g and the mass of the top block is 30g. The blocks move together (always touching each other) in two segments: o First with a velocity of 0.25 m/s upwards for 3.0 s o Then moving upwards but decelerating at 0.075 m/s² until they come to rest. Consider all forces acting on the top block, bottom block, and the hand. In each segment, rank the magnitudes of these forces. Note the direction of each force, and list any third-law pairs.
