Q2. Astronauts in space cannot weight themselves by standing on a bathroom scale. In its place, they determine their mass by oscillating on large spring. Assume 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.

a) What is her mass if the spring's constant is 240N/m?

b) What is her speed when the spring's length is 1, 2 m?
