A gardener holds a hose 0.75 m above the ground such that the water shoots out horizontally and hits the ground at the point 2.0m away. what is the speed with which the water leaves the hose
how long does it take to fall 0.75m?
4.9t^2 = 0.75
t = 0.39
so the speed of the water is
2.0/0.39 = ____ m/s
