At what point of a projectile motion acceleration and velocity are perpendicular to each other
At the point of projection
At the point of drop
At the topmost point
Any where in between the point of projection and topmost point
At what point of a projectile motion acceleration and velocity are perpendicular to each other
At the top most point of the projectile there is only horizontal component of velocity and acceleration due to gravity is vertically downward, so velocity and acceleration are perpendicular so each other.
