1. The problem statement, all variables and given/known data A table moves up and down in SHM of period 1 second. Find the amplitude it can have at which objects on the table just comence to lose contact with the table. 3. The attempt at a solution How do I need to solve this problem? I'm only given the period from which I can work out only the frequency [tex]f[/tex] and angular frequency [tex]\omega[/tex]. I know that the position of a particle that exhibits simple harmonic motion is given by [tex]x(t)=A cos (\omega t + \phi)[/tex] And I know the maximum value cosine can have is 1. But this is all I know, I don't see how I can approach this problem. Any help here is very much appreciated.
