You construct a dart gun using a spring that has a spring constant of 250 N/m. The dart you wish to launch has a mass of 0.3 kg, and compression length of the spring you design to be 0.4m. If you load and fire this dart from the dart gun, how fast will the dart's launch velocity be? Give your answer in units of m/s, however do not include the units explicitly in your answer. If you include units, the answer will be counted wrong.
