A snake observes an eagle perching on the top of a pole \( 20 \mathrm{~m} \) high. Its elevation from snake's eye is \( 45^{\circ} \)
\( \mathrm{P} \)
before it flies off horizontally straight away from the
W
snake and after one second the elevation of the eagle reduces to \( 30^{\circ} \). The speed of the eagle is
(1) \( 14.64 \mathrm{~m} / \mathrm{s} \)
(2) \( 17.71 \mathrm{~m} / \mathrm{s} \)
(3) \( 12 \mathrm{~m} / \mathrm{s} \)
(4) None of these
