Answer:
216 m/s
Explanation:
The jet is moving with uniform accelerated motion, so we can use the following suvat equation:
[tex]v=u+at[/tex]
where
v is the velocity at time t
u is the initial velocity
a is the acceleration
For the jet in the problem,
u = 78 m/s is the initial velocity
[tex]a=23 m/s^2[/tex] is the acceleration
Substituting t = 6.0 s, we find the final velocity:
[tex]v=78 + (23)(6.0)=216 m/s[/tex]
