Question

Jeff throws a ball straight up. For which situation is the vertical velocity zero?
a. on the way up
b. at the top
c. on the way back down
d. none of the above

Answer 1

Answer:

b. at the top

Explanation:

At the top of the climb, the vertical velocity of Jeff's throw has a value of zero.

Vertical velocity in this instance is acting against the acceleration due to gravity.

• At the top of the thrown, the force of the throw becomes zero and the velocity also becomes zero.
• As the body finds it way downward, it begins to fall freely.
• The fall is due to the acceleration due to gravity which is experienced by every object on earth.
