WebMar 27, 2024 · Vector projection is useful in physics applications involving force and work. Solution When the box is pulled by vector v some of the force is wasted pulling up against gravity. In real life this may be useful because of friction, but for now this energy is inefficiently wasted in the horizontal movement of the box. Example 2 WebIn Maculan et al. (Ref. 5), the problem of ﬁnding the projection of a vector on the simplex of n was deﬁned as a special quadratic programming problem. The authors presented an O(n) time algorithm. In Maculan et al.
