Answer:
s ≈ 35.8 m
Step-by-step explanation:
Let's apply the uniform acceleration equation to find the vertical height travelled after 2.7 seconds.
![s = ut + (1)/(2)at^2](https://img.qammunity.org/2023/formulas/physics/high-school/6000n17fazpbut3n7riykkap01ba8w6p0j.png)
s = distance travelled
u = initial vertical velocity
t = time taken
a = gravitational acceleration
The gun is fired horizontally, hence there is no initial vertical velocity.
![s = 0(2.7) + (1)/(2)(9.81)(2.7)^2](https://img.qammunity.org/2023/formulas/physics/high-school/av312baa9g3rfs3ar0yhcgfowvr6z48tyi.png)
![s = 35.75745 m](https://img.qammunity.org/2023/formulas/physics/high-school/kcw7ddp8ml7mokw2nga68e5mnzxzq1tcvs.png)
s ≈ 35.8 m
