A plastic cup,20.0 cm in height,is filled to the rim with water.A small hole is punctured in the cup at a height 12.00 cm above the bottom of the cup and is allowing water to spew out.What is the speed of the water as it exits the hole?

Question

The speed of the water can be calculated using Torricelli's theorem: v = √(2gh), where h is the height of the water column above the hole. Here, h = 20.0 cm - 12.0 cm = 8.0 cm = 0.08 m. Thus, v = √(2 * 9.8 m/s² * 0.08 m) ≈ 1.3 m/s.
