Answer:
I think the answer should be 72m.
Explanation:
Given- u=0, a=4 and t=6s
now,
we know that-
s=ut +at^2/2
s=0*6+4*6*6/2
s=36*2
therefore s=72m

Given :
Acceleration of boat = 3 m/s²
Time = 8 seconds
To Find :
The distance travelled by the boat during that time
Solution :
From second equation of motion ,
Where ,
u is initial velocity
t is time
a is acceleration
s is distance travelled
We have ,
u = 0 [starting from rest]
t = 8 sec
a = 8 m/s²
Substituting the values in the equation ,
Hence ,
The distance travelled by the boat during that time is 96 m.
