Physics - W.E.P. Question with Solution | TestHub

$F\propto s^{-1/3}$

i.e.,  acceleration$a\propto s^{-1/3}$

or$v\frac{\text{d}\mathit{\text{v}}}{\text{d}\mathit{\text{s}}}=\text{K}{\mathit{\text{s}}}^{-1/3}\text{ or}$${\text{v}}^2\propto {\text{s}}^{2/3}$

or$\mathit{\text{v}}\propto {\mathit{\text{s}}}^{1/3}$

Now$\mathit{\text{P}}=\mathit{\text{F.v}}$

or$\mathit{\text{P}}\propto s^{-1/3}\text{. }{\mathit{\text{s}}}^{1/3}\text{ or }\mathit{\text{P}}\propto s^0$

i.e., power is independent of s.
