$($in $k\frac{m}{h}r)$

C$.$ The angular velocity of the rope relative to the boat or $$ in $ra\frac{d}{s}.$ For fixed radius

$($circular$)$ motion like this $v=rd\frac{}{d}t.$

Ans: $v_S=80\mathrm{.}8\frac{km}{hr},$vec$(v_{\frac{S}{B}})=31\mathrm{.}93\frac{km}{hr},=0\mathrm{.}89\frac{\text{r}\text{a}\text{d}}{s}$
