Quinn is testing the motion of two projectiles x and y by shooting them from a sling shot. What can we say best describes the motion of the projectiles ? Assume air resistance is not a factor

Explanation:

            A projectile motion may be defined as that form of a motion that is experienced by an object or a particle which is projected near the surface of the Earth and the particle moves along the curved path  subjected to gravity force only.

           Thus a projectile motion is always acted upon by a constant acceleration due to gravity in the down ward direction.

             In the context, Quinn shoots two particle x and y from his sling shot and he observes that both his projectiles travels in a parabola curve in the air. Both the object x and y touches the ground a distance apart from him which is known as the range and it depends upon the velocity of the projectile. Both the projectile reaches a maximum height and then drop on the ground in a parabola shape.

B. The vertical velocity of projectile Y is changing, and the horizontal velocity of projectile X is constant.
