Question

At the top of the trajectory of a projectile, the directions of its velocity and acceleration are : (A) perpendicular to each other (B) parallel to each other (C) inclined to each other at an angle of 45° (D) antiparallel to each other

Tardigrade Admin · Accepted Answer

At the highest point of the trajectory of a projectile, only the horizontal component of velocity exists while vertical component is zero. Also, acceleration due to gravity acts vertically downwards, hence at the top of the trajectory of a projectile, the direction of its velocity and acceleration are perpendicular to each other.

parallel to each other

inclined to each other at an angle of $4 5^{\circ}$

antiparallel to each other
