This is question from A.P French vibrations and waves, problem 3-1 for anyone whom may have it
An object of mass 1 g is hung from a spring and set in oscillatory motion. At t=0 the displacement is 43.785 cm and the acceleration is -1.7514 cm/sec^2. What is the spring constant?
I thought this problem straight forward and used
using the numbers above but it gave the wrong answer? And I changed everything into S.I units I should also say
The answer is 0.025 N/m or 25 dyn/cm
I have been messing around with this for a while and gotten no where close to the correct answer!! Rather frustrating considering it is such a straight forward problem
Any help would be great thanks in advanced
