Thanks! :D

So Vf^2 = 31850? Vf = 178.47?

"A dragster accelerates from rest at 49 m/s^2. How fast is it going when it has traveled 325 m?" So, Vf^2 = V0^2 + 2aΔx I guess a=49 m/s^2 Δx would be 325? And its at rest? Would V0^2 be equal to 0 then? So then, Vf^2 = 0 + 2(49)Δ(325)?

Umm, well the question is asking how fast it is going... So I would have to use Vf = V0 + at or Vf^2 = V0^2 + 2aΔx? Or does it not matter which one I use?

Well so far, the formulas I've learned are: v= Δx/t a= Δv/t Xf= X0 + V0t Xf = X0 + V0t + 1/2at^2 Vf = V0 + at Vf^2 = V0^2 + 2aΔx

1. Homework Statement : A dragster accelerates from rest at 49 m/s^2. How fast is it going when it has traveled 325 m? I'm a complete beginner, I'm not really sure how to even approach this problem so please, with each step taken, provide a VERY detailed explanation of why and how you...
