1. The problem statement, all variables and given/known data

A particle's position on the x-axis is given by the function f(x) = (t^2 - 2t +4) where t is given in s. Where is particle at v= 4m/s?

2. Relevant equations

f(x) = (t^2 - 2t +4)

sf = si + vi(tf -ti) + .5a(tf-ti)^2

3. The attempt at a solution

d/dx f(x)= 2t - 2 = 4

2t = 6

t = 3

sf= 0 + 0(3) + .5(4/3)(3^2)
