Question

A gardener holds a hose 0,75m above the ground such that the waterfront out horizontally and hits the ground at a point 2 meters away, what is the speed with which the water leaves the hose.

Answer 1

123.56

Answer 2

How long does it take the water to hit the ground?

4.9t^2 = 0.75
t = 0.3912 seconds

so, the horizontal speed =
2m/.3912s = 5.11 m/s

Answer 3

G: dy=0.75m dx=2.0m
F: Vix=?
S: t=√2dy/g
=√2•0.75/9.8
=√1.5/9.8
=1.225/3.13
=0.391s
Vix=dx/t from dx=Vixt
=2.0÷0.391
=5.115m/s
