  1. 1.

    A lab technician tests two ideal springs, Spring X and Spring Y, where the spring constant of Spring Y is four times that of Spring X (kY=4kXk_Y = 4k_X). Both springs are gradually compressed from their relaxed equilibrium positions until they store the exact same amount of elastic potential energy. Based on this outcome, how do the compression distance and the magnitude of the restoring force of Spring Y compare to those of Spring X?

    • A) Spring Y is compressed by one-fourth the distance of Spring X, and Spring Y exerts the same restoring force as Spring X.
    • B) Spring Y is compressed by half the distance of Spring X, and Spring Y exerts twice the restoring force of Spring X.
    • C) Spring Y is compressed by half the distance of Spring X, and Spring Y exerts the same restoring force as Spring X.
    • D) Spring Y is compressed by twice the distance of Spring X, and Spring Y exerts four times the restoring force of Spring X.
