Two children are trying to shoot a marble into a small box using a spring-loaded gun that is fixed on a table and shoots horizontally from the edge of the table. The centre of the box is a horizontal
P distance \( 5 \mathrm{~m} \) from the edge of the table. The first child compresses the spring a distance \( 2 \mathrm{~cm} \) and finds that the marble falls short of its target by a horizontal distance \( 3 \mathrm{~m} \). By what distance \( \mathrm{x} \) should the second child compress the spring to score a direct hit on the box?
(1) \( 15 \mathrm{~cm} \)
(2) \( 10 \mathrm{~cm} \) (3) \( 4 \mathrm{~cm} \)
(4) \( 5 \mathrm{~cm} \)
