Hi there!

We can begin by solving for the time it takes the projectile to reach the ground.

Use the equation:

[tex]t = \sqrt{\frac{2h}{g}}[/tex]

Plug in the given height:

[tex]t = \sqrt{\frac{2(357)}{9.8}} = 8.536 s[/tex]

Use the equation:

d = vt, to solve for the horizontal distance:

d = (54)(8.536) = 460.944 m
