Since when we have the instantaneous acceleration, v1 and v2 should be about a fraction of a second apart, at that moment the direction is in fact dire ...

Lesson 8
... So why didn't we treat projectile motion using the concepts of centripetal and tangential acceleration? Because it makes the math harder to perform!! In Cartesian coordinates, the acceleration has only one component (vertical) and it is constant in magnitude. Thus, we can use the kinematic equations ...
