Unformatted text preview: brown (twb493) – Reflection 3 – turner – (57340) 1 This print-out should have 16 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 (part 1 of 9) 10.0 points What happens to the total energy of the mass- spring system as time increases? 1. It remains constant. correct 2. It oscillates. 3. It monotonically decreases. 4. It monotonically increases. Explanation: 002 (part 2 of 9) 10.0 points At what point in the mass’s trajectory is the kinetic energy a maximum? 1. at the spring-mass’s equilibrium position only on the way up 2. at both the highest and lowest points 3. at the spring-mass’s equilibrium position on the way up and down correct 4. at the spring-mass’s equilibrium position only on the way down 5. only at the highest point 6. only at the lowest point Explanation: 003 (part 3 of 9) 10.0 points At what point in the mass’s trajectory is the kinetic energy a minimum? 1. at both the highest and lowest points correct 2. at the spring-mass’s equilibrium position only on the way up 3. only at the lowest point 4. at the spring-mass’s equilibrium position only on the way down 5. only at the highest point 6. at the spring-mass’s equilibrium position on the way up and down Explanation: 004 (part 4 of 9) 10.0 points At what point in the mass’s trajectory is the potential energy a maximum? 1. at the spring-mass’s equilibrium position only on the way down 2. at both the highest and lowest points correct 3. at the spring-mass’s equilibrium position only on the way up 4. at the spring-mass’s equilibrium position on the way up and down 5. only at the lowest point 6. only at the highest point Explanation: 005 (part 5 of 9) 10.0 points At what point in the mass’s trajectory is the potential energy a minimum? 1. at the spring-mass’s equilibrium position only on the way up 2. only at the highest point 3. at the spring-mass’s equilibrium position only on the way down 4. only at the lowest point 5. at both the highest and lowest points brown (twb493) – Reflection 3 – turner – (57340) 2 6. at the spring-mass’s equilibrium position on the way up and down correct...
