Problem C8:
An object of mass m=2 Kg is subject to a force on the x-axis of the form
F_{x} = +k x, where k=2 Newtons/meter. When the object is at
the origin it's velocity is v_{0} = n_{1} meters/sec.
What is the objects speed v after it has traveled a distance d =
n_{2} meters on the x-axis. If v = n_{3} meters/sec,
What is n_{3}?
