Question

A ball is thrown into the air at some angle. At the very top of the ball's path, its velocity is
a. entirely vertical.
b. There's not enough information given to determine.
c. both vertical and horizontal.
d. entirely horizontal.

Answer 1

Entirely horizontal.

An object will continue to travel with the same velocity unless an external force is applied.
There are no external forces acting in the horizontal direction (except air resistance but the is negligable) so the ball will move in the horizonontal direction with with same speed at all times.
Force of gravity is acting downwards, meaning it is constantly acelleraring at 9.8ms^-2 towards the ground. When the ball reaches its heighest point, it is where the ball has stopped moving up and starts to move down, therfore it is not moving vertically at all.

Answer 2

When the ball should be thrown into the air so the velocity of the ball should be entirely horizontal.

The following information should be considered:

• The object should continue for travel having a similar velocity till the external force should be applied.
• Also, no external forces should be there in the case when it is horizontal direction except air resistance.
• The gravity force should be downwards at 9.8m/s^-2 towards the ground. At the time when the ball is at the highest point so the ball stops so, it can't be vertical.

Therefore, we can conclude that when the ball should be thrown into the air so the velocity of the ball should be entirely horizontal.
