Homework Statement



A ball is thrown horizontally at 16m/s from a clifftop 65m above the sea level.

Find
the time to land

Homework Equations



distance = Vi*t + at^2/2


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 !

"A ball is thrown horizontally..." What's the launch angle for a horizontally thrown projectile?
