(D) The average velocity is given by $\bar{v} = \frac{d}{t}$.Given $d = 100 \ m$ and $t = 10 \ s$,we have $\bar{v} = \frac{100}{10} = 10 \ m/s$.Assuming the mass of an athlete $(m)$ ranges from $50 \ kg$ to $100 \ kg$,we calculate the kinetic energy $(K = \frac{1}{2}mv^2)$:For $m_1 = 50 \ kg$: $K_1 = \frac{1}{2} 	imes 50 	imes (10)^2 = 25 	imes 100 = 2,500 \ J$.For $m_2 = 100 \ kg$: $K_2 = \frac{1}{2} 	imes 100 	imes (10)^2 = 50 	imes 100 = 5,000 \ J$.Thus,the estimated range of kinetic energy is $2,000 \ J - 5,000 \ J$.

In the Olympic games,an athlete covers a distance of $100 \ m$ in $10 \ s$. The estimated range of their kinetic energy is:
