For questions 1-4, assume there is a 3 m deep soil (in the slope-normal direction) with a density of 1600 kg/m³, cohesion of 18 kPa, and friction angle of 25°. The potential failure plane is the soil-bedrock interface, which is parallel to the surface and has a slope of 35°. As usual, acceleration due to gravity is 9.8 m/s², and water has a density of 1000 kg/m³.
