Question

a pump can throw a stream of water up to 29.6m. What is the initial speed of the stream when it leaves a hose nozzle?

Answer 1

is it in upward direction??

Answer 2

It doesn't specify, this is that is where I am stuck :/

Answer 3

i think it is because there is no other way to find initial velocity..

Answer 4

initial velocity=Vi=?
final velocity=Vf=0m/s
height=h= 29.6m
and for upward motion g= -9.8m/s^2
using third equation of motion
2gh=Vf^2 - Vi^2
2(-9.8)(29.6)= (0)^2 - (Vi)^2
-580.16= -Vi^2
Vi= sqrt (580.16)
Vi= 24.09 m/s
