I have no idea why I can not get this question, but here it is:
A brick is resting atop a piston that is moving vertically with simple harmonic motion of period 1.19 s. At what amplitude will the brick separate from the piston?
I know that once the acceleration is greater than that of gravity the 2 will seperate.
I tried using the equation:
a(t)=-w^2Acos(wt+phi) a=-9.8 w=2pi/T phi=pi and t=T
Where am I wrong on this question?
Any help would be greatly appreciated! Thanks
