At the highest point of the trajectory, which of the following quantities is zero?
Correct answer: C. Vertical velocity
- A. Horizontal velocity
- B. Total velocity
- C. Vertical velocity
- D. None of these options are correct
Explanation
The vertical velocity component of a projectile is 0 at a maximum height due to the action of acceleration due to gravity which acts in the direction opposite to that of the velocity and reduces its values constantly.Hence, C is the correct option

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
