Question

When is vertical velocity zero? Select all the apply

1. when an object changes direction.

2.the moment you kick a football in the air.

3. vertical velocity is zero initially when an object is dropped from a window.

4. the moment a ball rolls off a table.

5. the moment you throw a ball in the air.

Answer 1

Answer is 3

The velocity in the vertical direction begins to decrease as the object rises. At its highest point, the vertical velocity is zero. As the object falls toward Earth again, the vertical velocity increases again in magnitude but points in the opposite direction to the initial vertical velocity

Answer 2

3

Step-by-step explanation:

When the projectile reaches a vertical velocity of zero, this is the maximum height of the projectile and then gravity will take over and accelerate the object downward. The horizontal displacement of the projectile is called the range of the projectile, and depends on the initial velocity of the object.
