the Grand Canyon has the average death of 4000 ft with some sections going to 6000. If you drop an object from a Section 3300 above, how long (in seconds) will it take the object to hit the bottom?

Respuesta :

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
