Question

You have a toy that uses a spring to shoot darts. A dart has a mass of 5 g, and
the spring has a spring constant of 666 N/m. When loaded, the spring is compressed 5 cm from
its equilibrium position. You launch a dart horizontally. If the barrel of the dart gun exerts
14 N of friction on the dart, how fast is the dart traveling when it is launched?
