A boat travels to the right in a straight line away from a dock with an average acceleration of 12.0 m/s2. The boat then has it's engine stopped and the boat slows down at the same magnitude as it accelerated until it stops. The boat then turns around and travels back to the dock with the same average acceleration as before. Just as the boat reaches the dock the engine starts on fire. This slows the boat down with the same magnitude as it accelerated until it stops. Explain what the signs of each acceleration and deceleration should be for both traveling away and traveling toward the dock.

Classify the following soils according to the uscs classification system. provide appropriate uscs designations. a) this sample of well-graded gravel with sand was obtained from a large earthen dam in vancouver, canada. the sample has 73% fine to coarse sub-angular gravel, 25% fine to coarse sub-angular sand and 2% fines. the maximum size of the particles is 75 mm. the coefficient of curvature is 2.7, while the uniformity coefficient is 12.4. b) this dark brown and wet soil with a “strong organic odor” has 100% passing the no. 200 sieve. the liquid limit of the material is 32% when not dried and is 21% when oven-dried. the plastic index is 21% when not dried. c) this sand has 61% predominantly fine sand, 23% silty fines, and 16% fine sub-rounded gravel size. the maximum size is 20 mm. the liquid limit is 33% and the plastic limit is 27%. d) this soil has 74% fine to coarse sub-angular reddish sand and 26% organic and silty dark brown fines. the liquid limit is 37% when not dried and is 26% when oven dried. the plastic index is 6% when not dried.
