Answer:
The total momentum of the system before the collision is 5.334 kg-m/s towards left.
Explanation:
Given that,
Mass of the block A, 
Speed of block A, 
Mass of the block B, 
Mass of block B, 
Let p is the total momentum of the system before the collision. It is given by :

So, the total momentum of the system before the collision is 5.334 kg-m/s towards left. Hence, this is the required solution.
Here
Part B - 2
Answer all questions in this part. Directions (51 - 65): Record your answers in the spaces provided in your answer booklet. Some questions may require the use of the 2011 Edition Reference Tables for Physical Setting/Earth Science. Base your answers to questions 51 and 52 on the diagram and data table below, and on your knowledge of Earth science. The diagram represents the laboratory materials used for an investigation of the effects of particle size on water retention. Five separate columns were filled to the same level with particles. The particle type is indicated for each column. The particles within each column are of uniform shape. A volume of 50 milliliters (mL) of water was poured through each column, and the amount of water retained was determined. The data table shows the results of this experiment.
