Stone is thrown at +15 m/s from top of cliff at 44 meters high.
Im looking for the time it takes to reach the bottom and the final answer is 3 seconds. But I dont know how to get there.
Equation starts with
t^2 =2Y/g Y is initial height meaning -44 meters. The g is -9.80m/s^2. But where does the 2 come from? Is it always there in the formula?
