Randall D. Knight — Oscillations: Problem 46
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 P15.46. a. What is her mass if the spring constant is 240 N/m? b. What is her speed when the spring’s length is 1.2 m?
