To unload a tied pile of plywood from a truck, the driver first tilts the truck bed and then accelerates from rest. Knowing that friction coefficients between the bottom plywood layer and the bucket floor are s 0.40 and k 0.30, determine (a) the smallest acceleration of the truck that will cause the plywood pile to slide and (b) the acceleration of the truck that makes corner A of the plywood pile reach the end of the bucket in 0.9 s. I need the calculations and a detailed description substantiated and explaining each step of the calculations. Please. (If you have any way to make it easier to translate, I appreciate it. I can't read very well in english)
