Question

At the top of the trajectory of a projectile, thrown at an angle of projection $\theta <{90}^o$, its

• A. Velocity is zero
• B. Velocity is parallel to the direction of acceleration
• C. Velocity is anti-parallel to the direction of acceleration
• D. Velocity is perpendicular to the direction of acceleration

Answer 1

The correct option is D Velocity is perpendicular to the direction of acceleration

The velocity will be zero at the highest point of trajectory of a projectile because due to gravity any object come down and after reaching maximum height, the object stop for a certain time and then come back to the ground.
