Answer:

0.782 s

Explanation:

The water flows horizontally from the hose, so its initial vertical velocity is 0.

Given:

y₀ = 3 m

y = 0 m

v₀ = 0 m/s

a = -9.8 m/s²

Find: t

y = y₀ + v₀ t + ½ at²

0 m = 3 m + (0 m/s) t + ½ (-9.8 m/s²) t²

t = 0.782 s

Round as needed.

Answer:

0.782 seconds

Explanation:

Water flows horizontally from a hose that is 3m above the ground. The water lands 7.2m to the right of the hose. Therefore, it will take 0.782 seconds for the water to reach the ground. We know this because, the water flows sideways in the hose, therefore, making its vertical velocity 0.
