Perpendicular to each other

Vedclass · Answer

(A) The direction of velocity is always tangent to the path of the projectile. At the highest point of the trajectory,the vertical component of velocity becomes zero,so the velocity vector is purely horizontal.Acceleration due to gravity $(g)$ always acts in the vertically downward direction throughout the motion.Since the velocity is horizontal and the acceleration is vertical,the angle between the velocity vector $\vec{v}$ and the acceleration vector $\vec{g}$ is $90^o$.Therefore,they are perpendicular to each other.

At the top of the trajectory of a projectile,the directions of its velocity and acceleration are
