A hose has a hole of cross-sectional area 5cm^2 and ejects water horizontally at a speed of 0.3m/s. If the water is incident on a vertical wall and it's horizonal speed becomes zero, what force is exerted on the wall? At what water speed is the force sixteen times as small?
Uh... I don't know D-: F=ma, but I don't have the acceleration or the mass (well I have the acceleration, if it's 9.8m/s^2...)
How do you turn off the comments for imeem? Like, you know how you go to a playlist and at the bottom there's a box for sending comments in? Well, I know you don't have that for yours and I was wondering how you got it to be able to do that? Does that make sense? .-. Thanks for the help.
