g A canyon is 1200 meters deep at its deepest point. A rock is dropped from the rim above this point. How long will it take the rock to hit the canyon floor

t = 15.6 s

Step-by-step explanation:

According to the kinematic equation:

  (1)

Where:

: is the final position = 1200 m

y₀: is the initial position = 0 m

V₀: is the initial speed = 0 m/s

g: is the gravity = 9.81 m/s²

t: is the time =?

From equation (1) we have:

Therefore, it will take 15.6 seconds to the rock to hit the canyon floor.
