Question

a motor starting from rest on a lake acceleration along a straight line at a constant rate of 3 m/s2 for 8 s how far does the boat travel during this time

Answer 1

@
u=0
a=3m/s²
t=8sec
____________
s=ut+1/2at²
=>0*8+1/2*3*8²
=0+1/2*3*64
=3*32
=96 m
The boat will travel 96 metre .

Answer 2

u = 0
a= 3m/s^2
t= 8s
so now s= ut+1/2at^2
= 0(8) + (1/2×3×8×8)
= 0 + 96= 96m
