Question
The speed of an object traveling along the x axis increases at the constant rate of 3.5 m/s each second. At t = 0.0 s, its velocity is 1.3 m/s and its position is + 6.4 m.
a)How fast is it moving when its position is 8.0 m?
b)At this point, how much time has elapsed from the start at t = 0.0 s?

a = 3/5
v = 3/5 t + C
use v(0) = 1.3 to find C
s = 3/10 t^2 + Ct + D
use s(0) = 6.4 to find D
Now you can answer the questions.
