(Neglecting any water or air resistance) A waterfall is located 55 m downstream from where a boat is launched. If the speed of the river is 4 m/s, then what minimum boat speed is required to cross the 150m wide river before falling over the falls? What angle does the boat's path make with the shore? Assume constant speeds for the current and the boat.

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. a small hole is made in the side of each tank at the same depth 1.57 m below the liquid surface, but the hole in tank 2 has 2.49 times the cross-sectional area of the hole in tank 1. (a) what is the ratio ρ1/ρ2 of the densities of the liquids if the mass flow rate is the same for the two holes? (b) what is the ratio rv1/rv2 of the volume flow rates from the two tanks? (c) at one instant, the liquid in tank 1 is 14.9 cm above the hole. if the tanks are to have equal volume flow rates, what height above the hole must the liquid in tank 2 be just then?
