Answer:
19.5 m/s
Explanation:
The boat is moving with a uniform accelerated motion, therefore we can use the following suvat equation:
[tex]v=u+at[/tex]
where
:
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time
For the boat in this problem,
u = 3.2 m/s
[tex]a=6.5 m/s^2[/tex]
Substituting t = 2.5 s, we find the final velocity of the boat:
[tex]v=3.2 + (6.5)(2.5)=19.5 m/s[/tex]
