Problem
A mass of 2.0kg is hung from a single vertical light spring and produces a steady extension of 0.050m. The same mass is then hung from two identical springs connected in series, one below the other. Take g=9.8m s−2.
(i) Calculate the spring constant of one of the springs from the first arrangement.
(ii) Determine the total extension produced in the two-spring series arrangement by the same mass.
(iii) Calculate the total elastic potential energy stored in the two springs together in the series arrangement.
