Answer:
here we need to find distance
distance =speed x time
time = 6 sec (given)
speed= 4m per sec sguare ( acclaration is also speed)
here putting values
distance = 4 x 6= 24 m
the motarboat traved for 24 meter

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.
