Sagot :
Answer:
a = 1600 m / s²
Explanation:
For this exercise we use the kinematics relations,
v² = v₀² + 2 a x
where v₀ is the initial velocity of the bullet, which as part of rest is zero, for the distance (x) we can assume that the gases accelerate along the entire trajectory of the cannon x = 2m
a = [tex]\frac{v^2}{2x}[/tex]
let's calculate
a = [tex]\frac{80^2}{2 \ 2}[/tex]
a = 1600 m / s²
