Supposed you were standing beneath a palm tree when a coconut began to fall. If the height of the coconut is 64 feet, how much t
larisa [96]

Answer:

t = 1.41 seconds

Step-by-step explanation:

We know the height at which the coconut is, which is 64 ft, now assuming that we are on the ground, we know that gravity is equal to 32.1742 ft / s².

Gravity is an acceleration, we have that the acceleration is equal to:

a = v / t

but the speed v = d / t, replacing we have:

a = (d / t) / t

That is to say

a = d / t²

Now, solved for you we have:

t = (d / a) ^ (1/2)

Replacing the values, we are left with:

t = (64 / 32.17) ^ (1/2)

t = 1.41 seconds

therefore, the person has 1.41 seconds to escape.
