Homework Statement
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
Homework Equations
Constant acceleration equationsv = vo + at
x = xo + vo t + ½ a t2
xo + ½ (v + vo) t
2 a (x - xo)= v2 - vo2
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.
