Answer:
96 m
Explanation:
so in this case this is just started so u=0
a is given 3m\s
t is 8 sec
using 1 equation v=u+at
v= 0+24
v=24m
now find s
using 3 equation vsqure-usquare=2as
putting value 576-0=2(3)s
576\6=s
s=96

Answer:
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.
