For general projectile motion, the horizontal component of a projectile's accelerationGroup of answer choicesremains a non-zero constant.continuously decreases.continuously increases.is zero.any of the above, depending on position.

For general projectile motion, when the projectile is at the highest point of its trajectoryGroup of answer choicesits acceleration is zero.none of theseits velocity is perpendicular to the acceleration.the horizontal component of its velocity is zero.its velocity and acceleration are both zero.the horizontal and vertical components of its velocity are zero.

While an object is in projectile motion (with upward being positive) with no air resistanceGroup of answer choicesthe vertical component of its velocity remains constant and the vertical component of its acceleration is equal to -g.none of thesethe vertical component of both its velocity and its acceleration remain constant.the horizontal component of its velocity remains constant and the vertical component of its acceleration is equal to -g.the horizontal component of its velocity remains constant and the horizontal component of its acceleration is equal to -g.the horizontal component of its velocity remains constant and the vertical component of its acceleration is equal to zero.

In projectile motion the horizontal component of velocity: a. Remains constant b. Decreases with time c. Changes uniformly d. Increases with time

Which of the following statements is true for the acceleration of the projectile (of the previous question)?Group of answer choicesIt is zero in horizontal and g downward in vertical directionIt is g downward in both horizontal and vertical directionsIt is g downward in horizontal direction and zero in vertical directionIt is zero in horizontal and g upward in vertical directionIt is zero in both horizontal and vertical directions
