Question

An oscillator consists of a block attached to a spring(k=400N/m). At some time t, the position (measured from theequilibrium position), velocity, and acceleration of the block arex = 0.190m, v = -13.6m/s,
and a = -123 cm/s2.
a) What is the frequency of the oscillation?
b) What is the mass of the block? Ignore the mass of thespring.)
c) What is the amplitude of the motion? An oscillator consists of a block attached to a spring(k=400N/m). At some time t, the position (measured from theequilibrium position), velocity, and acceleration of the block arex = 0.190m, v = -13.6m/s,
and a = -123 cm/s2. a) What is the frequency of the oscillation? b) What is the mass of the block? Ignore the mass of thespring.) c) What is the amplitude of the motion?

Explanation / Answer

Position x = 0.019 m

Velocity v = -13.6 m / s

Accleration a= -123 cm / s^ 2

                     = -1.23 m / s^ 2

(a). frequency of oscillations   f = ?

We know a = xw^ 2
