Amplitude of the oscillation
Another question, this is about mass on helical spring
A mass is attached to the wall by a spring of constant k. When the spring is at its natural length, the mass is given a certain initial velocity, resulting in oscillations of Amplitude A. If the spring is replaced by a spring constant 2k and the mass is given the same initial velocity, what is the amplitude of the resulting oscillation?
Ans : a) A√2
b) 2 A√2
c) A√2 /2
d) (3/2) A√2
e) (2/3) A√2
using the formula I've found this : A' = A sin √2Ѡt
Please help...
