A cubical box of wine has a small spout located in one of the bottom corners. When the box is full and placed on a level surface, opening the spout results in a flow of wine with a initial speed of v subscript 0 end subscript (see figure). When the box is half empty, someone tilts it at 45° so that the spout is at the lowest point (see figure). When the spout is opened the wine will flow out with a speed of

A cylindrical block of area of cross–section A and of material of density rho is placed in a liquid of density one–third of density of block. The block compresses a spring and compression in the spring is one–third of the length of the block. If acceleration due to gravity is g, the spring constant of the spring is:
