1. The problem statement, all variables and given/known data A ball is thrown horizontally at 16m/s from a clifftop 65m above the sea level. Find the time to land 2. Relevant equations distance = Vi*t + at^2/2 3. The attempt at a solution I separated x and y components. And tried to plug them in this formula. I thought maybe I will have 2 unknowns and will then resolve it by plugging the equation in the other. But I realized I had 3 unknowns since they don't give me the angle. So, I can't find the components of the initial speed. Maybe, I am using the wrong formula ? Thanks in advance !
