Texts: Question #2 (4 pts). A Modified Proctor compaction test was conducted on the soil, with the results shown below. The weight and volume of the mold used in the test were 4.85 lb and 1/30 ft, respectively, and the mass of the can was 50 grams. Based on the results: a) Plot the Proctor curve for the borrow soil. (2 pts) b) Determine the optimum water content and maximum dry unit weight for the borrow soil. (1 pt) c) Determine whether the unit weight of the top layer can be met by compacting to 95% of maximum, and what the range of moisture content for that unit weight is.

Assignment 2 PHY2333 due Tuesday, Sept. 29, 2020 A. A block of mass $m$ is free to move along a horizontal x-axis. At the time $t = 0$ the block is at rest at the origin. The block experiences a constant applied force of propulsion $F$ in the positive x-direction, and also a force of air resistance with magnitude given by $cv^2$. Derive the velocity $v$ of the block as a function of position $x$, and also find the position at which the block has reached 4/5 of its final (i.e. terminal) speed.
