An object is shot vertically upward.While it is rising:

C)its velocity and acceleration are both downward
D)its velocity is downward and its acceleration is upward
E)its velocity and acceleration are both decreasing

Question

Quizplus · Accepted Answer

When an object is shot vertically upward, it will initially have a positive velocity (upward), but its acceleration will be negative (downward) due to the force of gravity acting on it. As the object rises, its velocity will decrease until it reaches its maximum height (at which point the velocity will be zero), and then it will start falling back down. During this descent, both the velocity and acceleration will be downward. However, while the object is rising, its velocity is still upward, but its acceleration is downward. Therefore, choice B is the correct answer.

An Object Is Shot Vertically Upward
