A body is thrown with some velocity from the ground.
Maximum height attained when it is thrown at \( 60^{\circ} \) to the horizontal is \( 90 \mathrm{~m} \). What is the height attained when it is thrown at \( 30^{\circ} \) to the horizontal ?
(1) \( 90 \mathrm{~m} \)
(2) \( 45 \mathrm{~m} \)
(3) \( 30 \mathrm{~m} \)
(4) \( 15 \mathrm{~m} \)
\( \mathrm{P} \)
