I. In projectile motion, the angle between instantaneous velocity vector and acceleration vector can be anything between 0 to $π$ (excluding the limiting case.)
II. In projectile motion, acceleration vector is always pointing vertically downwards. (Neglect air friction).
Which of the following statement{s) is/are correct?

Question

Infinity Learn · Accepted Answer

For oblique projection ,the angle between instantaneous velocity vector and acceleration vector before attaining the maximum height is obtuse and after  the maximum height is attained , it is obtuse . At the highest point, it is perpendicular $$($$π$$/2)$$.For vertically upward projection ,initial angle between velocity and acceleration is π and at the end of flight , this angle becomes $$00$$.
