Answer:
a = - 50 [m/s²]
Step-by-step explanation:
To solve this problem we simply have to replace the values supplied in the given equation.
Vf = final velocity = 0.5 [m/s]
Vi = initial velocity = 10 [m/s]
s = distance = 100 [m]
a = acceleration [m/s²]
Now replacing we have:
![(0.5)^(2)-(10)^(2) = 2*a*(100)\\0.25-10000=200*a\\200*a=-9999.75\\a =-50 [m/s^(2) ]](https://img.qammunity.org/2021/formulas/physics/high-school/pkwea1nrzrb44weyrblfdo5b6hzsbs7rp8.png)
The negative sign of acceleration means that the ship slows down its velocity in order to land.
