Consider the same four blocks (A-D) which are all more dense than the fluid. Rank, from smallest to largest, the time for the blocks to reach the bottom of the container (tA , tB , tC , and tC ). You may find it helpful to draw free body diagrams and use Newton’s laws for each block. If any of the situations have equal times, clearly indicate this in your ranking. Please explain how you got this answer.
