Homework Statement
Hey peeps, I'm really struggling with this one and I'm looking for a point in the right direction.
A mass of 0.3 kg is suspended from a spring of stiffness 200 N m¯¹. If the mass is displaced by 10 mm from its equilibrium position and released, for the resulting vibration,
(iv) the mass required to produce double the maximum velocity calculated in (ii) using the same spring and initial deflection.
Homework Equations
Am i right in assuming that i need to use a transposition of the following formula to find mass,
f=1/2pi√ k/m
The Attempt at a Solution
This is where i struggle as I am having a blonde moment and just can't seem to start this one.
so far i have,
frequency of 4.109
time of 0.243
velocity of 0.25819
accelecration of 6.666
New velocity of 0.51638 (2x.25819)
