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
Correct Answer: A
Solution :
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.You need to login to perform this action.
