Amass of 0.14 kg is attached to a spring and set into oscillation on a horizontal frictionless surface. the simple harmonic motion of the mass is described by x(t) = (0.28 m)cos[(8 rad/s)t]. determine the following. (a) amplitude of oscillation for the oscillating mass .

The amplitude of oscillation for the oscillating mass is 0.28 m.

Explanation:

Given that,

Mass = 0.14 kg

Equation of simple harmonic motion

....(I)

We need to calculate the amplitude

Using general equation of simple harmonic equation

Compare the equation (I) from general equation

The amplitude is 0.28 m.

Hence, The amplitude of oscillation for the oscillating mass is 0.28 m.
