A 2.00 kg mass attached to a spring is driven by an external force F = (2.00 N) cos (3t). Assume that the force constant of the spring is 25.0 N/m.
(a) Determine the period of the motion
(b) Determine the amplitude of the motion
FOr part A, i tried the T=2(pi)/w formula, and i got the wrong answer...what am i doing wrong?
For part B, the book says to use this formula:
A= Fo/m / square root of [ (w^2-wo^2)+(bw/m)^2 ]
the Bw/m^2 is irrelevant since B=0...
But what is Fo? Is this how u are suppose to solve for the amplitute for this problem? thanks
