64 meters
If a ball is thrown horizontally at 20 m/s from the top of a cliff that is 50 meters high, the ball will strike the ground 64 m from the base of the cliff (20m/s x 3.2 s).
64 METERSA+
The ball was thrown horizontally at 10 meters per sec, and the thrower's arm was 78.4 meters above the base of the cliff.
10 m/s
Answer: 44 meters
"3.2" or "3.20" please put all of that

It doesn't matter whether the object is thrown down, up, horizontally, or diagonally. Once it leaves the thrower's hand, it is accelerated downward by an amount equal to acceleration of gravity on the planet where this is all happening. On Earth, if you throw an object horizontally, it accelerates downward at the rate of 9.8 meters per second2 ... just as it would if you simply dropped it. Whether it's dropped or thrown horizontally, it hits the ground at the same time.
The rock will have a greater speed when it reaches the ground level compared to the ball thrown horizontally because the rock will be accelerated by gravity as it falls vertically, while the ball thrown horizontally will only have its initial horizontal velocity.
the time it takes to get to ground is s = 1/2 at^2 where a is gravity acceleration of 9.8 m/s/s and s is 50 meters and t^2 is time squared.Solve for time t = 3.2 secondsThe horizontal distance from base of cliff is h = vt where h is distance and v is velocity = 20 m/sh = 20 x 3.2 = 64 meters

if the bal is thrown by making 45 degree angles. with the ground..it will travel maximum distance...
They should reach the ground together, since their initial vertical speed is the same, namely zero.
