Question

LEARN MORE REMARKS As the analysis of part (a) shows, the speed of the water emerging from the hole is equal to the speed acquired by an object falling freely through the vertical distance h. This is known as Torricelll's law. QUESTION As time passes what happens to the speed of the water leaving the hole? It remains the same. It first decreases and then increases. It decreases It first increases and then decreases. It increases. PRACTICE IT Use the worked example above to help you solve this problem. A nearsighted sheriff fires at a cattle rustler with his trusty six-shooter. Fortunately for the rustler, the bullet misses him and penetrates the town water tank, causing a leak (see figure). (a) If the top of the tank is open to the atmosphere, determine the speed at which the water leaves the hole when the water level is 0.470 m above the hole. m/s (b) Where does the stream hit the ground if the hole is 2.75 m above the ground? EXERCISE HINTS: GETTING STARTED I I'M STUCK! Suppose, in a similar situation, the water hits the ground 4.15 m from the hole in the tank. If the hole is 1.55 m above the ground, how far above the hole is the water level? m above the hole Need Help? Read It Talk to a Tutor
