Explanation:
Integrate with respect to 't' the accel function to get the velocity function:
velocity = v/7 t + c1 when t = 0 this =1 so c1 = 1
velocity = v/7 t + 1 integrate again to find position function
s = v/14 t^2 + t + c2 when t = 0 this equals 2 so c2 = 2
s = v/14 t^2 + t + 2
( Let me know if this is incorrect and I will re-evaluate)
