1. The problem statement, all variables and given/known data
a ball is thrown horizontally with a speed of 15m/s at a point 2.0m above the level ground. how far will it go before it hits the ground

2. Relevant equations
Dt = (Vi)(t) + (1/2)(a)(t^2)

3. The attempt at a solution

i think this is the formula to use, however, i dont have a time.

Apply the eqn for horizontal and vertical components of motion. you'll get the time.

But you have another equation involving time, namely x = vxt.

So use the equation you gave to find the time it takes before it hits the ground (think carefully about what the initial velocity is that you should plug in) and then insert the time you found in neutrino's formula to find the horizontal distance.
