An spacecraft is flying horizontally at a uniform velocity of \( 300 \mathrm{~m} / \mathrm{s} \). If the angle subtended at
\( \mathrm{P} \) an observation point in the same vertical plane

W on the ground by two positions of the spacecraft \( 20 \mathrm{~s} \) apart is \( 74^{\circ} \), what is the height of the aircraft above the ground? It is given that spacecraft is vertically above the observer after \( 10 \mathrm{~s} \).
(1) \( 3 \mathrm{~km} \)
(2) \( 4 \mathrm{~km} \)
(3) \( 5 \mathrm{~km} \)
(4) \( 7 \mathrm{~km} \)
