A popular game in Indian villages is goli which is played with small glass balls called golis. The goli of one player is situatted at a distance of 2.0 m from the goli of the second player. This second player has to project his goli by keeping the thumb of the left hand at the place of his goli, holding the goli between his two middlefilngers and making the throw. If he projected is 19.6 cm from the ground and the goli is to be projected horizontally, with what speed shold it be projected so that it directly hits the stationary goli without falling on the ground earlier?

Explanation

To solve the problem, we need to determine the horizontal speed at which the goli should be projected so that it hits the stationary goli without falling to the ground. Here’s a step-by-step solution:

### Step 1: Understand the problem
The goli is projected horizontally from a height of 19.6 cm (which is 0.196 m) and must travel a horizontal distance of 2.0 m before hitting the stationary goli.

### Step 2: Calculate the time of flight
To find the time it takes for the goli to fall to the ground, we can use the formula for the time of flight under gravity:
