PHYS131_Tank-2.jpg Suppose we have a very large tank of water (density 1000 kg/m3) that's filled up to a height of 3 m. The tank is open at the top. Take g = 9.8 m/s2. Suppose we punch a hole (area 0.5 cm2) at point 1, which is at height 1.5 m. What is the velocity of the water as it exits this hole? Group of answer choices 2.6 m/s 1.5 m/s 3.4 m/s 4.7 m/s 5.4 m/s
