Question

Which of the following statement is correct in connection with projectiles?

• A. A path traced by a projectile in space is known as trajectory.
• B. The velocity with which a projectile is projected is known as velocity of projection.
• C. The angle with the horizontal at which a projectile is projected is known as angle of projection.
• D. all of the above

Hint:

The horizontal component of the velocity of projection ($u \cos \alpha$) always remains constant throughout the flight because there is no horizontal force (like air resistance) acting on it.

Answer 1

The Correct Option is D
