A 2.0 kg particle moving along the x-axis experiences the force shown in FIGURE EX9.22. The particles velocity is 4.0 m/s at x = 0 m. What is its velocity at x = 2 m and x = 4 m?
Topic: Weathering Takes longer in dry environments; accelerates in wet environments Types of Weathering: 1) Mechanical/Physical: breakup of rock into smaller rocks a. Frost Wedging: involves expansion and contraction of water in rock crack due to freezing and thawing b. Frost heaving: Up thrust of sediment or soil due to the freezing of wet soil beneath c. Salt crystal growth: involves buildup of salts on rock surfaces through evaporation. Salt weakens the rock, making it vulnerable d. Exfoliation: sheets of rock flake away due to seasonal temperature changes or by the expansion of rock due to unloading 2) Chemical: dissolves the rock a. Oxidation: oxygen chemically combines
