A Weight Hanging on a Spring Will Oscillate Up and Down

Multiple Choice

A weight hanging on a spring will oscillate up and down about its equilibrium position after it's pulled down and released. This is an example of simple hormonic motion. This motion would continue forever if there wasn't any friction or air resistance. Simple harmonic motion can be described with the function

Where A is the amplitude, t is the time in seconds, m is the mass and k is a constant particular to that spring. If a spring is measured in centimeters and the weight in grams, then what are the amplitude and mass if

Amplitude: _____cm.
Mass: ______ g.

A) Amplitude: 5.5 cm.; mass:g.
B) Amplitude: 5.5 cm.; mass:g.
C) Amplitude: 30.25 cm.; mass:g.
D) Amplitude: 30.25 cm.; mass: 77.44 g.
