Part A 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 What is her mass if the spring constant is 270 N/m ? 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 Express your answer with the appropriate units. astronaut then pulls her away from the wall and releases her. The spring's length as a function of time is shown in the figure (Figure 1). m= Value Units Submit Request Answer Part B What is her speed when the spring's length is 0.70 m ? Express your answer with the appropriate units. Figure
