In the figure, a spring-block system is put into SHM in two experiments. In the first, the block is pulled from the equilibrium position through a displacementd1 and then released. In the second, it is pulled from the equilibrium position through a greater displacementd2 and then released. Are the
(a) amplitude,
(b) period,
(c) frequency,
(d) maximum kinetic energy, and
(e) maximum potential energy in the second experiment greater than, less than, or the same as those in the first experiment?
