Answer :

Final answer:

The question relates to the field of Physics, specifically kinematics. It pertains to the motion of a ball kicked upward with 68 feet per second initial velocity. Its movement can be studied through principles of free fall and Newton's laws of motion.

Explanation:

The subject of this question pertains to the motion of a ball kicked upward with an initial velocity of 68 feet per second. This falls under the category of Physics, specifically the subtopic of kinematics which studies the motion of objects. The motion of this ball will follow the principle of free fall. When an object is projected upward, the velocity of the ball decreases until it reaches its maximum height, at which point the velocity is zero. Afterwards, the ball will begin falling back down, slowly increasing its velocity due to acceleration caused by gravity. Using the principles of physics, we can calculate different aspects of the ball's motion such as its maximum height, the time it takes to reach that height, its velocity at any given time, etc. Such calculations would typically involve formulas derived from Newton's laws of motion.
