Dart #3, shot straight up from a spring-loaded toy dart gun, ascends a distance of 24 meters before coming back down. Dart #4, identical to #3, is shot straight up from the same gun, but this time the spring is compressed only half as far before firing. How far up does dart #4 go? Neglect all friction and assume the spring to be ideal.
