I think nincompoop's profile picture matches your question and it's tilting it's head to read what you wrote :P

@IrishBoy123 please help

i;ve already done the question but the answer is different

- YumYum247

what have i done wrong??????

- imqwerty

well the car is deaccelerating so u need to take the acceleration as -2.3m/s^2 :)

- YumYum247

ok let me try the question that way and i;ll get back to you

- imqwerty

ok :)

- imqwerty

try to think this way -
if the car ws accelerating instead of deaccelerating then it wuld have certainly covered more distance.
so if u try to calculate the distance covered by the accelerating car u wuld apply this formula- S=ut +1/2 at^2
but u r applying the same formula for deaccelrating car so u r getting the same distance nd this is not possible so u can conclude that u made a mistake while taking the sign of acceleration :)

got it......i got the answer Thanks man :)

@Astrophysics LOL my question was pretty easy, maybe she has a sprained neck or something.

- Astrophysics

Haha, yes, kinematics problems aren't too difficult, the problem most people have with this is, the terms, and knowing what they mean. it can get confusing I guess, when you're dealing with average velocity, instantaneous velocity, displacement, distance, deceleration, etc =P

- Astrophysics

So for now you can think of deceleration as negative acceleration

- Astrophysics

deceleration = - a

- YumYum247

got it...actually i've this this unit before but yah i guess i forgot about this particular thing LOL :D

- Astrophysics

Haha, yeah but if you want to be technical, deceleration really just means decrease in speed, I really don't like this term though xD.

- YumYum247

me neither....!!! XD
