A stone is projected from the ground with velocity \( 25 \mathrm{~m} / \mathrm{s} \). Two seconds later, it just clears a wall \( 5 \mathrm{~m} \) high. The angle of projection of the stone is \( \left(\mathrm{g}=10 \mathrm{~m} / \mathrm{sec}^{2}\right) \)
(1) \( 30^{\circ} \)
(2) \( 45^{\circ} \)
(3) \( 50.2^{\circ} \)
(4) \( 60^{\circ} \)
