Center of Mass of Particles
Q1) Find the xcm coordinate of the center of mass of the system of particles shown in the figure.
Express your answer in meters to two significant figures.
Q2) A straight rod has one end at the origin and the other end at the point (L,0) and a linear density given by lambda = ax^2 , where is a known constant and is the x coordinate. Since this wire is not uniform, you will have to use integration to solve this part. Use this integration formula to find the total mass . Find xcm for this rod.
Express your answer in terms of one or both of a and L .
