scoray [572]

Answer:

<h2>760 m/s</h2>

Explanation:

The jet's speed or final velocity can be found by using the formula

<h3>v = u + at</h3>

where

v is the final velocity

u is the initial velocity

t is the time taken

a is the acceleration

From the question we have

v = 600 + 20(8)

= 600 + 160

We have the final answer as

<h3>760 m/s</h3>

Hope this helps you
