Answer:

The ball will hit the ground after 1.54 seconds

Step-by-step explanation:

This is a form of projectile motion in horizontal direction

Thus, time taken to reach the ground

[tex]t = \sqrt{\frac{2*d}{g} }[/tex]

Substituting the given values in above equation, we get -

[tex]t = \sqrt{\frac{2* 12}{10} } \\t = 1.54[/tex]seconds
