Aperson throws a rock at 3 m/s down over the edge of a very tall cliff on earth how far will the rock have fallen in 4 seconds if the rock never hit the bottom?

The rock will be at 90.4 m from the top of the cliff.

Explanation:

The rock is thrown with the “initial velocity” 3 m/s. We need to find how much distance does the rock traveled in 4 seconds (t).

From the “kinematic equations” take

Where, “s” is distance traveled, “u” initial velocity of the object, “t” time the object traveled and “a” acceleration due to gravity is

Substitute the given values in the above formula,

The rock is at height of 90.4 m from the top of the cliff.
