Question: During heavy rain, a section of a mountainside measuring 4.5 km horizontally (perpendicular to the slope) 0.92 km up along the slope, and 0.68 m deep slips into a valley in a mud slide. Assume that the mud ends up uniformly distributed over a surface area of the valley measuring 0.97 km x 0.97 km and that the mass of a cubic meter of mud is 1900 kg.
Part A: What is the mass of the mud sitting above a 4.9 m2 area of the valley floor?
Please show all work and steps to calculate the mass of the mud. Thanks.
