Aspring of constant k hangs from a ceiling with a mass m attached at the other end. the natural length of the hanging spring without the mass is l. a) draw this scenario, including forces and known or calculable displacements. b) what is the equilibrium length of the spring with the mass attached? c) suppose the spring is pulled down to create a displacement y from this equilibrium position and then released. write an expression y (t) describing its position as a function of time t. let "up" be the positive vertical direction. d) what is the period of oscillation for this simple harmonic oscillator? e) suppose you cut the spring in half. what would be the spring constant of each half-spring? (the two are identical, so they will have the same spring constant.) to determine this, redraw your diagram as two springs of equal length connected "in series," i. e., top to bottom. then indicate the forces acting on each of the three interesting bodies: the mass m and each halfspring of constant k’. apply hooke’s law to each half-spring individually and then to the two springs together. f) take the two half-springs from part e) and connect them "in parallel" (that is, side by side, hanging from the ceiling and each connected to the mass m). draw the new diagram and repeat parts a) - d)
