Textbook Question

Chapter 7, Problem 6MCP

Two identical objects are pressed against two different springs so that each spring stores 50 J of potential energy. The objects are then released from rest. One spring is quite stiff (hard to compress), while the other one is quite flexible (easy to compress). Which of the following statements is or are true? (More than one statement may be true.)

A. Both objects will have the same maximum speed after being released.
B. The object pressed against the stiff spring will gain more kinetic energy than the other object.
C. Both springs are initially compressed by the same amount.
D. The stiff spring has a larger spring constant than the flexible spring.
E. The flexible spring must have been compressed more than the stiff spring.
