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 monotonically decreases. 2. It monotonically increases. 3. It oscillates. 4. It remains constant. correct Explanation: 002 (part 2 of 9) 10.0 points At what point in the mass’s trajectory is the kinetic energy a maximum? 1. only at the lowest point 2. at the spring-mass’s equilibrium position only on the way up 3. only at the highest point 4. at both the highest and lowest points 5. at the spring-mass’s equilibrium position only on the way down 6. at the spring-mass’s equilibrium position on the way up and down correct Explanation: 003 (part 3 of 9) 10.0 points At what point in the mass’s trajectory is the kinetic energy a minimum? 1. only at the highest point 2. at the spring-mass’s equilibrium position on the way up and down 3. at both the highest and lowest points correct 4. at the spring-mass’s equilibrium position only on the way up 5. only at the lowest point 6. at the spring-mass’s equilibrium position only on the way 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 the spring-mass’s equilibrium position only on the way up 3. at the spring-mass’s equilibrium position on the way up and down 4. at both the highest and lowest points correct 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 down 2. at both the highest and lowest points 3. at the spring-mass’s equilibrium position only on the way up 4. only at the lowest point 5. at the spring-mass’s equilibrium position on the way up and down correct pasha (sep635) – Model 3 Reflection – Antoniewicz – (56445)...
