1. The problem statement, all variables and given/known data A dragster starts from rest and travels 0.25 miles in 6.7 s. Assuming that the acceleration is constant, what is its speed (in miles per hour) at this point? Δt= 6.7 s Δx= .25 miles 2. Relevant equations Constant acceleration equations v = vo + at x = xo + vo t + ½ a t2 xo + ½ (v + vo) t 2 a (x - xo)= v2 - vo2 3. The attempt at a solution all of the relevant constant acceleration equations I have in front of me have too many variables to isolate one given this. I know I can figure Vavg .25/0.00186111 hrs (6.7 s.) = 134.3284 but this doesn't do me any good. If you could nudge me in the right direction I would appreciate it.
