Problem B8:
An object starts from rest at the origin of the x-axis. The object has an acceleration
in the x-direction that depends on time as: a_{x} = n_{1} +6t. The
units of a_{x} and n_{1} are m/sec^{2}. The units of t are
sec. After a time of n_{2} seconds, the object is at the position
n_{3} meters on the x-axis. What is n_{3}?
