5. a small first-aid kit is dropped by a rock climber who is descending steadily at 1.3 m/s.
after 2.5 s, what is the velocity of the first-aid kit, and how far is the kit below the
climber?

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.
