Astronauts in space cannot weigh themselves by standing on a bathroom scale. Instead, they determine their mass by oscillating on a large spring. Suppose an astronaut attaches one end of a large spring to her belt and the other end to a hook on the wall of the space capsule. A fellow astronaut then pulls her away from the wall and releases her. The spring's length as a function of time is shown in (Figure 1). Figure Part B What is her speed when the spring's length is \( 1.3 \mathrm{~m} \) ? Express your answer with the appropriate units.
