A 4.63 kg block moves in a straight line in the positive direction of an x-axis while an applied force F→a acts on it. The force is directed along the negative direction of the x-axis and has magnitude Fa=9.6x + 2.3x2, with x in meters and in Fa newtons. If the initial kinetic energy of the block is 200 J, find the kinetic energy of the block after it starts at the position x=0 and moves to x=3.3 m.
