\[x _{f}=x _{i}+v _{1}\Delta t+\frac{ 1 }{ 2 }a \Delta t ^{2}\]

a would be the acceleration.

what would it be in this case though? like what number?

Actually the first equation you should use is this one \[v _{f}=v _{i}+a \Delta t\]

this will help you compute your acceleration.

ohh so first we solve for acceleration and then plug it into the other formula?

VeritasVosLiberabitBest ResponseYou've already chosen the best response.1
then you could actually just use the formula \[v _{f}^{2}=v _{i}^{2}+2a \Delta x\] and compute the total distance.

so you actually won't even need the first formula, so you can disregard it.

what did u end up getting for acceleration because i got 4 and then did the problem and got it wrong..

VeritasVosLiberabitBest ResponseYou've already chosen the best response.1
the answer is not 4.

i dont mind reposting it so i could give u the best answer but would u mind helping me?

sure. could you make a new thread for it though? This one is cluttered now.
