# conservation of energy multiple choice

Learning Goal: To practice Problem-SolvingStrategy 7.2 Conservation of energy with conservative forces.

A basket of negligible weight hangs from a vertical spring scale offorce constant 1500 . If you suddenly put an adobe brick of mass3.00 in the basket, find the maximumdistance that the springwill stretch.Which of the following statements about theproblem are true?
1. The spring is initially unstretched.
2. After the brick has been placed in the basket, the spring isstretched.
3. When the brick is first placed into the basket, it has zerovelocity.
4. When the brick has stretched the spring to its full extent, ithas zero velocity.
5. The brick’s final position is lower than its initialposition.

Learning Goal: To learn to apply the law ofconservation of energy to the analysis of harmonic oscillators.Systems in simple harmonic motion, or harmonicoscillators, obey the law of conservation of energy just likeall other systems do. Using energyconsiderations, one can analyzemany aspects of motion of the oscillator. Such an analysis can besimplified if one assumes that mechanical energy is notdissipated.In other words,,where is the total mechanical energy of the system, is the kinetic energy, and is the potential energy.As you know,...
