Answer:
The value is [tex]a = -3.7 \ m/s^2 [/tex]
Explanation:
From the question we are told that
The landing speed is [tex]u = 71.9 \ m/s[/tex]
The distance traveled is [tex]d = 675 \ m[/tex]
The velocity it is reduced to is [tex]v = 11.3 \ m/s[/tex]
Generally the average acceleration is mathematically represented as
[tex]a = \frac{ v^2 - u^2 }{ 2 * d }[/tex]
=> [tex]a = \frac{ 11.3^2 - 71.9^2 }{ 2 * 675 }[/tex]
=> [tex]a = -3.7 \ m/s^2 [/tex]
