It is desired to transport an aquarium tank in a car. The car can accelerate uniformly from rest
with an acceleration of a=g. The length and width of the tank are 2c and w, respectively.
What should be the maximum possible height of the water that can be retained in the
aquarium tank during transportation without spilling any water.
HINT: a_(x)=-(1)/(\rho )(delp)/(delx)+g_(x), and ,a_(z)=-(1)/(\rho )(delp)/(delz)+g_(z)
