Physics - Kinematics Question with Solution | TestHub

A boat on one bank of the river wants to reach other bank of river flowing with speed $v_0$. Speed of boat in still water is also ${\mathrm{v}}_0$. Boat moves in such a way that its distance from a fixed point P remains constant equal to 2 d . Time taken to cross the river is $\frac{\mathrm{d}}{{\mathrm{v}}_0}\ln \left(\mathrm{x}+\sqrt{{\mathrm{x}}^2-1}\right)$, value of x , is
