Hello, Not being in a math classroom for some 50 years now, I am struggling to find the most proper solution for the following. It requires some math/geometry and/or perhaps physics knowledge that I have likely forgotten (or never learned to begin with). Attached Figure 1 shows one example that needs to be adequately solved for. It is a preliminary analysis of upward movement of an object away from the ground, represented in vector form and as selected from video frames of the movement. At frame 170 (the green 170 circle and starting point), both vectors are one and the same. The movement then progresses through frame 185 (the green 185 circle and end of the desired analysis period). Two notable movement types have taken place. One is a rotational aspect that creates a rotation p...
