a weight of 20 N, moves from point A to point B on a smooth surface of a path in a three-dimensional space. The x- y- and z- coordinates of the points are given respectively in meters: A (0: 3: 3), B (6: 5; 0). The speed of the object at point A is 18m/s and the force [F = 2x² i+ 3y² j+z² k] N is acting on the object during the motion. What is the speed of the object at point B?
