1.
What effect does increasing the mass have on the angular frequency of the oscillation?
2.
Write the equation for angular frequency and explain how changing the spring constant
could affect the angular frequency. Confirm your conclusions by changing the spring
and repeating one of your previous runs using the same mass.
The motion of a mass and spring is described by the following equation:
11y"+4y+6y= 35 cos(yt)
Identify the value of y that would produce resonance in the system. Give an exact value, but you don't
need to simplify radicals.
Y
What is the amplitude of the steady-state solution when the system is at resonance? Round your answer to
two decimal places.
The amplitude is
If there was no external force, the oscillation of the spring could be described in the form A sin(ßt + p).
What is the value of B? Give an exact value, but you don't need to simplify radicals.
В
A spring with spring constant k = 12 slug/s2 has a mass attached that stretches the spring 2-2/3 ft. The damping coefficient is 7 slug/s. The mass is pushed 1 ft above the rest position and then released with a velocity of 1 ft/s downward.
set up the differential equation that describes the motion under the assumption of this section. Solve the differential equation. State whether the motion of
the spring system is harmonic, damped oscillation, critically damped oscillation, or overdamped. If the motion is overdamped oscillation, rewrite in the amplitude-phase form.

After release, the pendulum makes one complete back-and-forth cycle in 2 sec and follows simple harmonic motion. What is the period of motion? What is the frequency? What is the amplitude?
