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.

Question

I am having trouble ranking these four blocks. The answer key says: Least C < D < A < B Greatest but I can't figure out how to solve it to get that answer. 

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. 

M = 50 g
V₁ = 10 cm³
M₂ = 80 g
V₁ = 20 cm³
Mc = 80 g
V = 10 cm³
M₁ = 80 g
V₂ = 15 cm³
Transcribed Image Text:M = 50 g V₁ = 10 cm³ M₂ = 80 g V₁ = 20 cm³ Mc = 80 g V = 10 cm³ M₁ = 80 g V₂ = 15 cm³
