$2\sqrt 3 \,m/s$

Vedclass · Answer

$x^{2} y^{2}=\ell^{2}$

$2 \mathrm{x} \frac{\mathrm{dx}}{\mathrm{dt}}+2 \mathrm{y} \frac{\mathrm{dy}}{\mathrm{dt}}=2 \ell \frac{\mathrm{d} \ell}{\mathrm{dt}}$

$\mathrm{xU}_{\mathrm{x}}+\mathrm{yU}_{\mathrm{y}}=0$

$\mathrm{U}_{\mathrm{y}}=-\frac{\mathrm{x}}{\mathrm{y}} \mathrm{U}_{\mathrm{x}}$

$=-	an 	heta \mathrm{U}_{\mathrm{x}}=	an 60 	imes \mathrm{U}_{\mathrm{x}}$
