The average height of an apple tree is 4.00 meters. how long would it take an apple falling from that height to reach the ground? given: g = -9.8 meters/second2

The time is 0.90 sec.

Explanation:

Given that,

Height = 4.00 m

We need to calculate the time

Using equation of motion

Where, s = height

g = acceleration due to gravity

t = time

Put the value into the formula

Hence, The time is 0.90 sec.

it doesn't. it was imagined up in the middle ages.
