A) linearly related to time
B) inversely proportional to time
C) inversely proportional to the square of time
D) a constant
Correct Answer: A
Solution :
Given, force \[(F)\propto \frac{1}{v}\] or \[ma=\frac{k}{v}\] or \[m\times \frac{v}{t}=\frac{k}{v}\] or \[m{{v}^{2}}=kt\] or \[\frac{1}{2}m{{v}^{2}}=k't\] \[\Rightarrow \] \[KE\propto t\]
