Density of Water. ﬂ”)? — 1000 kU/i'ﬂ V] i: E s} 3 pi); A gardener holds a hose a height h = 1.25 meters above the ground. A stream of WﬂIBI' leaves the hose, traveling horizontaily, and hits the ground a distance L 2.16 meters from the gardener. a} What is the speed v of thc water as it Ieaves the hose? (Hint: The water behaves iike an object in projectile motion, like you studied in Physics 6A.) {If you can‘t figure out this part, make up an}.r reasonable answer so you can continue with part b) You examine the hose more closely. The main part of the hose has a radius r1: 2 em. The nozzle is narrower, with a radius r3: {.15 em. hail-in boil“ CI”?— h) In part (a), you calculated the speed 122 of the water leaving the nozzle. What is the speed v! of the water in the main part of the hose? e) What is the pressure .’-"Jr of the water in the main boo},r of the hose? (Him: the water leaving the nozzle is in direct contact, with the air, so it must have the same pressure as the atmosphere outside?) ...

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
