Homework Statement
A ball was thrown from a cliff, it reached to the ground after 2.5 seconds.
a) Find the height of the cliff.
b) Find the horizontal distance the ball reached.
Homework Equations
Δy = 2⋅g⋅t^2
Vfy = g⋅t
√(Vfy)^2+(Vfx)^2
Δx= Vx⋅t
The Attempt at a Solution
I've found Δy=30.6m and Vfy=24.5m/s but I couldn't find Vfx without Δx using the equation Δx=Vx⋅t
How can I find Vfx in order to calculate Vf
