Answer :B) remains a non-zero constant

For a projectile launched horizontally, the vertical component of a projectile’s velocity
A) is zero.
B) remains a non-zero constant.
C) continuously increases.
D) continuously decreases.
E) any of the above, depending on position.

For a projectile launched horizontally, the horizontal component of a projectile’s velocity
A) is zero.
B) remains a non-zero constant.
C) continuously increases.
D) continuously decreases.
E) any of the above, depending on position.

Answer :B) remains a non-zero constant.

A ball rolls off the edge of a table. The horizontal component of the ball’s velocity remains constant during its entire trajectory because
A) the ball is not acted upon by any force.
B) the net force acting on the ball is zero.
C) the ball is not acted upon by a force in the horizontal direction.
D) the ball is not acted upon by a force in the vertical direction.
E) None of the other choices is correct.

Answer : C) the ball is not acted upon by a force in the horizontal direction.
