A projectile is projected with velocity u at an angle θ with the vertical. At what point velocity and acceleration will be perpendicular to each other?

Solution

At the highest point the velocity is in horizontal direction and acceleration is in vertically downward direction. Hence, velocity and acceleration of projectile are perpendicular to each other at the highest point.
