Find equations giving the position x, the acceleration a, and the force acting in the x direction as functions of time. The velocity of an object moving along a line (you can call the line the x axis) is given by v = va + vb*sin(ωt), where ω = 0.2 rad/sec, va = 1.4 m/sec, and vb = 3.2 m/sec. At time t = 0, the position x0 = 1.2 meters.
