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.
