Adart of mass 0.5 kg is pressed against the spring of a dart gun the spring k=300n/m is compressed 10 cm and released. if the dart detaches from the spring when the latter reaches its normal length what speed does the dart acquire?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
