the Grand Canyon has the average depth of 4000 ft with some sections going to 6000.
i.e. distance = 4000 ft
goind speed = 6000ft/sec
If the object is fall from the 3300 feet above the bottom
Thus total distance travelled by the object = 4000-3300
Distance travelled = 700 feet
Speed = Distance/Time
Substitute the value
6000=700/time
Time = 700/6000
Time= 0.116 second
Answer: it take the object to hit the bottom in 0.11 seconds
