Paula drops a pebble into the ocean from a 120ft high cliff. Use the formula t=h−−√4 to find how many seconds it takes for the pebble to reach the ocean. Round your answer to the nearest tenth of a second.

Respuesta :

Answer:

2.7 seconds

Step-by-step explanation:

We are asked to find how many seconds it takes for an object to fall from a height of 120ft. We will use the given formula, t=h−−√4. Substituting h=120, we find

t=120−−−√4=2.7

So, the pebble reaches the ocean after 2.7 seconds.
