Part A. Find the force constant of the springPart B. Find the mass of the astronaut

In order to study the long-term effects of weightlessness. astronauts in space must be weighed (or at least 'massed ). One way in which this is done is to seat them in a chair of known mass attached to a spring of known force constant and measure the period of the oscillations of this system. The 34.4-kg chair alone oscillates with a period of 1.50 s. and the period with the astronaut sitting in the chair is 2.21 s
