A straight rod has one end at the origin and the other end at the point (L,0) and a linear density given by λ=ax^2, where a is a known constant and x is the x coordinate. Since this wire is not uniform, you will have to use integration to solve this part. Use M=∫L0dm to find the total mass M. Find xcm for this rod. Express your answer in terms of one or both of a and L.
