Astronauts in space cannot weight themselves by standing on a bathroom scale. Instead, they determine their mass by oscillating on 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.

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

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