A hole is poked through the metal side of a drum holding water.The hole is 28 cm below the water surface.What is the initial speed of outflow?
A) 1.9 m/s
B) 2.3 m/s
C) 3.2 m/s
D) 3.5 m/s

The initial speed of outflow can be calculated using Torricelli's law: v = √(2gh), where g is the acceleration due to gravity (9.8 m/s²) and h is the height of the water column above the hole (0.28 m). Plugging in the values, v = √(2 * 9.8 * 0.28) ≈ 2.3 m/s.
