Answer:
4.84615 m
Explanation:
Here the linear momentum is conserved and it is assumed that they will meet at the center of gravity of the system.
The center of gravity is given by
[tex]R=\frac {1}{M}\sum _{i=1}^{n}m_ir _i[/tex]
where
i = Particle
m = Mass
r = Position
n = Number of particles
The father's location is taken as reference
[tex]R=\frac{(0\times 85)+(45\times 14)}{85+45}=4.84615\ m[/tex]
The father will be 4.84615 m from the origin.
