Collisions in two dimensions is a difficult section to read and understand. But, when we look at momentum similarly to our 'Sum of our Forces', then we can use the same concept to solve these problems. This means that the momentum in the x direction before the collision has to be as the momentum after the collision. The momentum in the y direction before the collision has to be as the momentum after the collision.1. True2. False

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 Ο1/Ο2 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?
