Problem
Two identical masses are attached separately to spring A and spring B. Spring A has twice the force constant of spring B. Both masses are displaced the same small amount and released from rest. Which of the following best describes how their periods compare?
(a) The period of spring A is 2 times that of spring B.
(b) The period of spring A is 21 that of spring B.
(c) The period of spring A is 21 that of spring B.
(d) The period of spring A is the same as that of spring B.
