Question: An object is moving along the x - axis with acceleration ( in the positive x - direction ) of a ( t ) =

An object is moving along the x-axis with acceleration (in the positive x-direction) of a(t)=-18t+8 feet per second per second for 0t13. At t=3 the object is at position x=29 feet and its velocity in the positive direction is -40 feet per second.
Find the position of the object when t=7.
Position:
