Problem $2(2$ points$)($category: fluids in rigid body motion$)$: A tank full of milk is being transported. The

length parallel to the direction of travel is $7$ m and the height is $3$ m $.$ If the milk fills the tank up to $2\mathrm{.}75$

m $,$ what is the maximum acceleration$/$deceleration to avoid the milk hitting the top of the tank?

Problem $3(2$ points$)($category: FE prep, fluids in rigid body motion$)$: A $30$ cm diameter, $40$ cm high

vertical cylindrical container is filled with water up to $25$ cm $.$ Then, the cylinder is rotated at a constant

speed of $15ra\frac{d}{s}.$ Calculate the height of the water at the center and the edge of the cylinder.
