The velocity of a projectile at any instant (t) is given by _.
Correct answer: A. Option A: The sum of horizontal and vertical velocity at the particular point.
- A. Option A: The sum of horizontal and vertical velocity at the particular point.
- B. Option B: The initial velocity of the projectile.
- C. Option C: The acceleration of the projectile.
- D. Option D: The angle of projection of the projectile.
Explanation
The correct answer is Option A. The velocity of a projectile at any instant is the sum of its horizontal and vertical velocity components at that specific point in time. The other options do not accurately describe the concept of velocity at any given instant.

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.
