Answer:
h= 2582.9 m
Explanation:
bullet kinematics: bullet moves with uniformly accelerated movement in freefall
The negative sign in the equation indicates that the acceleration (g) is in the direction opposite to the movement of the bullet.
v f₁²=v₀²-2g*h₁ Equation (1))
h: hight in meters (m)
v₀: initial speed in m/s
vf: final speed in m/s
Known data
v₀= 225 m/s
g= 9.8 m/s² : acceleration due to gravity
Problem development
When the bulletl reaches the maximum height the final speed is equal to zero. vf=0
We replace data in the equation (1)
v f₁²=v₀²-2g*h₁
0 = (225)²-2*9.8*h
2*9.8*h=(225)²
h= (225)²/ (2*9.8)
h= 2582.9 m
