(a) X- coordinate of center of mass = (m1*x1 + m2*x2 + m3*x3) / (m1 + m2 + m3)
= (2.3*0 + 4.0*2.0 + 9.0*1.0) / (2.3+4.0+9.0)
= (0 + 8.0 + 9.0) / 15.3
= 1.11 m
Y- coordinate of center of mass = (m1*y1 + m2*y2 + m3*y3) / (m1 + m2 + m3)
= (2.3*0 + 4.0*1.0 + 9.0*2.0) / (2.3+4.0+9.0)
= (0 + 4.0 + 18.0) / 15.3
= 1.44 m (Answer)
(b) Third option, the center of mass shifts toward the topmost particle' is the correct answer.
Explanation -
when, m3 will be larger, coordinates of m3 will be considerable in respect to the coordinates of m1 and m2. Therefore, coordinate of center of mass will move towards m3.

The figure below show three masses m1=1.1 kg, m2=2.8 kg, and m3=4.3 kg which undergo two successive collisions. The first collision between m1, which has an initial velocity v=8.2 m/s, and m2 (which is initially at rest) is completely inelastic. The second collision between the combined mass m1+m2 and m3 (which is initially at rest) is elastic. What is the velocity of m3 after the second collision?
