Suppose you adjust your garden hose nozzle for a hard stream of water. You point the nozzle vertically upward at a height of $1.5 m$ above the ground (the hose is $1.5 m$ off the ground). When you quickly move the nozzle from the vertical you hear the water striking the ground next to you for another $2.1 s$ .What is the water speed as it leaves the nozzle?

College Math problems only seem challenging at first, yet what they truly represent is not much harder than high school Math with some equations that are closer to the engineering approach. Approaching your college math helper is essential because your questions may just have to be worded differently. Regardless if you are dealing with equations or need answers to your college math questions, taking a look at college math equations will let you see things differently. Approach college math answers step-by-step. The majority of college math problems with answers represented here will be similar to what you already have.
