Answer:
[tex]5 m/s^2[/tex]
Explanation:
The acceleration of an object is given by
[tex]a=\frac{v-u}{t}[/tex]
where
v is the final velocity
u is the initial velocity
t is the time it takes for the velocity to change from u to v
For the boat in the problem,
v = 10 m/s
u = 0
t = 2 s
Substituting, we find the acceleration
[tex]a=\frac{10-0}{2}=5 m/s^2[/tex]
