C. The maximum elastic potential energy will be at a positionbetween the highest point and equilibrium, and also between thelowest position and equilibrium.

D. The maximum elastic potential energy will be both at thehighest position and lowest position from the earth during itsmotion.

E. The maximum elastic potential energy will only be at theequilibrium position during its motion. 2. A ball of negligible size and a given mass is attached to avertical spring that obeys Hooke's law. At equilibrium, itsposition and gravitational potential energy is chosen to be \"zero\".The mass is set in oscillation in a vertical direction. At whatpoint during the oscillation will the ball-earth-spring system havethe most negative gravitational potential energy? A. The gravitational potential energy will be the most negativeat its lowest position from the earth. B. The gravitational potential energy can be zero but willnever be negative. C. The gravitational potential energy will be the most negativeat both the highest position and lowest position from theearth. D. The gravitational potential energy will be the most negativewhen the system stops moving. E. The gravitational potential energy will be the most negativeat its highest position from the earth. 3. Why doesn't the spring in a typical mountain bike shockabsorber continue to vibrate (bounce up and down) after a riderhits a bump? A. Because it converts the spring's elastic potential energyinto gravitational potential energy. B. Because it converts the spring's elastic potential energyinto internal energy of damping oil. C. Because it converts the spring's elastic potential energyinto kinetic energy of the rider. D. Because it converts the elastic potential energy in thespring on one side of the bike to elastic potential energy in thespring on the other side of the bike. E. Because the spring in a mountain bike shock absorber isspecially designed so that it never has any elastic potentialenergy. 4. Which of the descriptions below is an example of resonantenergy transfer? (Choose all that are correct.) A. A box is pushed with a constant force down an emptyabandoned hallway and its speed increase. B. A vibrating pendulum connected to a very similar secondpendulum influences the vibration of the second pendulum. Theamplitude of vibration of the first pendulum decreases and theamplitude of the second increases. This exchange of amplitude andenergy keeps happening back and forth between the twopendulums. C. Ultrasound machines are used to apply a variable force at afrequency that matches the natural frequency of gall stones,causing the gall stones to vibrate and break up. D. Soldiers marching in unison on a bridge with their steps ata frequency that is very different than the naturalvibration frequency of the bridge. E. A block sliding on a horizontal surface slows down and comesto a stop due to the friction force. 5. In a longitudinal wave... A. the vibrational motion of the particles is parallel to thedirection of propagation of the disturbance.
