GIVEN THE FOLLOWING PROBLEM
Conceptual Example 8 takes advantage of energy conservation to illustrate what
happens to the maximum speed, amplitude, and angular frequency of a simple harmonic
oscillator when its mass is changed suddenly at a certain point in the motion.
Conceptual Example 8 Changing the Mass of a Simple Harmonic Oscillator
Figure 10.18a shows a box of mass m attached to a spring that has a force constant k. The box
rests on a horizontal, frictionless surface. The spring is initially stretched to x = A and then
released from rest. The box executes simple harmonic motion that is characterized by a maximum
speed max, an amplitude A, and an angular frequency w. When the box is passing through
the point where the spring is unstrained (x = 0 m), a second box of the same mass m and speed
max is attached to it, as in part b of the drawing. Discuss what happens to (a) the maximum speed,
(b) the amplitude, and (c) the angular frequency of the subsequent simple harmonic motion.
Reasoning and Solution (a) The maximum speed of an object in simple harmonic motion
occurs when the object is passing through the point where the spring is unstrained (x = 0 m),
as in Figure 10.18b. Since the second box is attached at this point with the same speed, the
maximum speed of the two-box system remains the same as that of the one-box system.
(b) At the same speed, the maximum kinetic energy of the two boxes is twice that of a single
box, since the mass is twice as much. Subsequently, when the two boxes move to the left and
compress the spring, their kinetic energy is converted into elastic potential energy. Since the
two boxes have twice as much kinetic energy as one box alone, the two will have twice as much
elastic potential energy when they come to a halt at the extreme left. Here, we are using the
principle of conservation of mechanical energy, which applies since friction is absent. But the
elastic potential energy is proportional to the amplitude squared (4²) of the motion, so the
amplitude of the two-box system is √2 times as great as that of the one-box system.
(c) The angular frequency w of a simple harmonic oscillator is w = √k/m (Equation 10.11).
Since the mass of the two-box system is twice the mass of the one-box system, the angular
frequency of the two-box system is √2 times as small as that of the one-box system.

and speed, is attached.
Answer why the Amplitude of the mass-spring system increased to 2 times the mass is sqrt(2) greater than that of the
one-mass system and the angular frequency is sqrt(2) times less than that of the one-mass system.
