Question

What is the horizontal acceleration of a ball that is launched horizontally with a velocity of 5.6 m/s?

Answer 1

Once it leaves the bat, the club, or the hand, there is no
horizontal force on it (ignoring air resistance). So it has
no horizontal acceleration (ignoring air resistance).

Answer 2

Step-by-step explanation:

When an object is launched under the action of gravity, the path followed by it is called projectile motion. The horizontal component of velocity is given by :

`v_x=u_i\ cos\theta`

`\theta` is the angle made with horizontal

In case of projectile motion, the velocity of projectile is constant in horizontal direction. As a result the rate of change of velocity will be equal to 0. So, the horizontal acceleration of a ball that is launched horizontally is 0. Hence, this is the required solution.
