A gardener holds a hose 0.75m above the ground such that the water shoots out horizontally and hits the ground at appoint 2.0 m away. What is the speed with which the water leaves the hose?

Answer 1

so, how long does it take to fall 0.75 meters?

4.9t^2 = 0.75

Using that time value, the constant horizontal speed is

2.0m/ts = 2.0/t m/s
