Sounds like the situation is modeled like so:
[Light] - - - - - - - - - - [You] => - - -
- - - - - - - - - - - - - - - [Cop] - - - - -
<= = = 200 m = = =>
where your velocity is 27.8 m/s to the right. So the question is asking, is it possible that your car, given that it accelerates at a maximum of 1/5 m/s^2, can reach a speed of 27.8 m/s from rest in the time it takes for it to cover 200 m.
The car's position at time 
is
The time it takes to traverse 200 m is
Your car's velocity at time , starting from rest, is
so that after 16.3 s, your car is moving at a speed of
which is less than the speed the cop claims you were going, so the cop is not correct.

Hello,
The mass number is protons+neutrons=mass number. In this case, we have protons+nuetron=164.The atomic number is simply the number of protons so we have 43+neutrons=164. Subtracting 43 from both sides we get nuetrons=121. Hope this helps!

More water evaporates than falls as rain
did u know 3 million tonnes of water gets evaporated from oceans per day
