Question

Help please
It’s kinda urgent

Answer 1

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) ]`

The negative sign of acceleration means that the ship slows down its velocity in order to land.
