Three beads are placed along a thin rod. The first bead has a mass m1=28g placed at a distance d1= 0.7 cm from the left of the rod. The second bead of mass m2= 11g is placed at a distance d2= 2.5 cm to the right of the 1st bead. The third bead has a mass m3=55g at a distance d3=4.1cm to the right of the second bead. Assume an x-axis that points to the right.
A. Write a symbolic equation for the center of mass of the three beads relative to the center bead.
B. Calculate the numeric value of location of the center of mass relative to the middle bead in cm.
