**Problem Statement:**A mother has four times the mass of her young son. Both are running with the same kinetic energy.**Question:***Part A*What is the ratio \( v_s / v_m \) of their speeds?\[ v_s / v_m = \]**Explanation:**This problem involves understanding the relationship between mass, speed, and kinetic energy. According to the kinetic energy formula, \( KE = \frac{1}{2}mv^2 \), when two objects have the same kinetic energy, their speeds relate inversely to the square root of their masses.Given:- The mother’s mass \( m_m = 4m_s \) (four times the son's mass).- Kinetic energy \( KE_m = KE_s \).You need to find the speed ratio \( v_s / v_m \).

Let the mass of mother is and mass of son is The kinetic energy of the son and mother is the same.To…
