Answer: 96 m
Explanation:
Given
Initial velocity u= 0 m/s
Acceleration a= 3 m/s^2
Time t = 8 sec
Displacement s=?
Apply motion second equation
s= ut +1/2 at^2
= 0 +3×8×8/2
= 96 m

Given, initial velocity of boat is: u=0
Acceleration is: a=3 ms^2
Time is: t=8 s
Using second equation of motion:
s=ut+ 1/2at^2
s=0×8+ 1/2×3×8^2 =96 m.
