How far away from the telephone pole was Same when it fell across the road?
What was Sam's acceleration
How long did it take for him to stop?

Show steps, not just the answer, thanks.

anonymous · Answer

what is the 3s?

anonymous · Answer

3 seconds

anonymous · Answer

what i am asking you is what does it represent?

anonymous · Answer

if you have the velocity he is travelling at and the time, you can solve for the distance. and also the acceleration

anonymous · Answer

v=s/t
so t*v=s
and 
a=v/t

anonymous · Answer

it represents that it's 3 seconds away from the other vehicle. i'm not understanding your equations.
