## Homework Statement

A small bock that has a mass equal to M rest on a piston that is vibrating vertically with simply harmonic motion described by the formula y = Asin(wt)

a) Show that the block will leave the piston if w

^{2}A > g.

b) If w

^{2}A = 3g and A = 15 cm, at what time will the block leave the piston?

## Homework Equations

F = m*a (maybe...)

## The Attempt at a Solution

The only thing I did was find that the equation for the acceleration is,

a = -w

^{2}Asin(wt)
