A student throws a ball horizontally at the rate of 40 m/s. If the height from which the ball is thrown is 2 m, how far will the ball travel before it touches the ground? a-16.33m
b-19.54m
c-25.56m
d-28.29m

The correct option is C

Explanation:

From the question we are told that

  The speed of the ball in the horizontal direction is  

   The height from which the ball is thrown is s =  2 m

Generally from kinematic equation

Here u is the initial  velocity of the ball and this zero  given that the ball was at rest before it was thrown.

So

=>  

Generally the distance the ball will travel before touching the ground is  

=>    

=>
