A $5-$gal, cylindrical open container with a bottom area of $120$in$\mathrm{.}2$is filled with glycerin and rests on

the floor of an elevator. $($a$)$Determine the fluid pressure at the bottom of the container when the

elevator has an upward acceleration of $2\mathrm{.}0$ft$/$s$2.($b$)$What resultant force does the container exert on

the floor of the elevator during this acceleration? The weight of the container is negligible. $($Note:

$1$gal $=231$in
