An object of mass m and speed vo strikes a rigid uniform rod of length l and mass mr that is hanging by a frictionless pivot from the ceiling. Immediately after striking the rod, the object continues forward but its speed decreases to vo/2. The moment of inertia of the rod about its center of mass is ML2/12 . You may express your answer in terms of m, mr, g and l. Answer all the following in terms of the given quantities and any physical constants.(Submit a file with a maximum size of 1 MB.)a. For what value of vo will the rod just touch the ceiling on its first swing?b. For what ratio of mr/m will the collision be elastic?

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.
