A gardener holds a hose 0.75 m above the ground such that water shoots out horizontally and hits the ground at a point 2 m away. What is the speed with which the water leaves the hose?

Answer 1

123.56

Answer 2

Solution please?

Answer 3

how long does it take to fall 0.75m?
4.9t^2 = 0.75

the speed is 2/t m/s

I don't think the above answer is correct.

Answer 4

I calculated it as 5.11 m/s is that right?

Answer 5

given
dy= -0.75m
dx= 2m
g= 9.8 m/s²

sol
vx

formula dx=vxt
dx/t=vxt/t
vx=dx/t

solve for t
form; square root of 2dy/g
t= square root of 2(-0.75m)/-9.8m/s²
t=0.39s

vx= dx/t
v= 2m/39

answer= 5.13 m/s
