(a)
The average acceleration of the ship is given by
where
v is the final velocity
u is the initial velocity
t is the time elapsed
Here we have:
is the initial velocity
v = 0 is the final velocity
is the time elapsed
Substituting, we find
(b) 4.72 m/s
Assuming the acceleration is uniform, the average velocity of the ship is given by:
where
v is the final velocity
u is the initial velocity
Here we have:
v = 0
u = 9.44 m/s
So the average velocity of the ship is
