velocity vibrations.

samedi 28 septembre 2013

1. The problem statement, all variables and given/known data

A mass of 0.3kg is suspended from a spring of stiffness 200Nm-1. If the mass is displaced by 10mm from its equalibrium position and released, for the resulting vibration calculate: The maximum velocity of the mass during the vibration.

2. Relevant equations

v = Aωcos(wt+∅)

3. The attempt at a solution

Now ω = 25.82cos.

so v = A 25.82cos (25.82t+∅)

So now i have to find A (amplitude) and t (displacement)

Is displacement the same as the amplitude?

Not sure on how to find the amplitude? Any guidance would be appreciated.
