A block rides on a piston that is moving vertically with simple harmonic motion. $($a$)$ If the SHM has period $1\mathrm{.}98$ s $,$ at what amplitude of motion will the block and piston separate? $($b$)$ If the piston has an amplitude of $2\mathrm{.}17$ cm $,$ what is the maximum frequency for which the block and piston will be in contact continuously?
