) Given that the peak elevation was approximately 2450 m prior to the event (and valley floor elevation at 1250 m, and 1.55 km horizontal distance from the peak) calculate the normal force and the shear force of a boulder approximately 4m by 3m by 8m on the top of the slope prior to the event. Assume that the density of the boulder was 2400 kg/m3. Use the vertical (dv) and horizontal distance (dh) from the peak to the valley floor (as shown in the conceptual diagram) to calculate the hypotenuse and the value of cos and sin. Please show: dv, dh, the slope hypotenuse, the boulder mass, the normal force and shear force
