Assignment:
Question 1. A mass sits on a frictionless table. It is attached to a wall by a spring. The mass is initially located at x = 0 when the spring is unstretched (equilibrium position). You pull the mass away from the equilibrium position, out to x = A, and then release it. The mass then oscillates horizontally back and forth in simple harmonic motion.
Which of the statements below are true about this motion?
(Give ALL correct answers: B, AC, BCD .., or None)
A) The speed of the mass is maximum at x = 0
B) The total energy of the mass-spring system at x = A is the same as the total energy at x = 0
C) Simple harmonic motion can also be referred to as periodic motion
D) The potential energy of the mass-spring system is maximum at x = 0
E) The magnitude of the acceleration of the mass is maximum at x = A
