Answer:

b. at the top

Step-by-step 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.
