A spring-loaded dart gun is used to shoot a dart straight up into the air, and the dart reaches a maximum height of 24 meters above its point of release. The same dart is shot up a second time from the same gun, but this time the spring is compressed only half as far (compared to the first shot). How far up does the dart go this time? (Neglect friction and assume the spring is ideal and massless.)

the dart goes 6m deep
Explanation:
1/2 k x1² = mgh1 (1)
1/2 k x2² = mgh2 (2)
Dividing 1 by 2 gives the relation
(x1/x2)²= h1/h2
using given
[x/ (x/2)]²=24/h2
4= 24/h2
h2=6 m
