Answer:
760 m/s
Step-by-step explanation:
The jet's speed or final velocity can be found by using the formula
v = u + at
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
760 m/s
Hope this helps you
