Question

The average height of an apple tree is 4.00 m how long will it take for an apple falling from that height to reach the ground given G equals -9.8 m a second squared

Answer 1

The time taken for the apple to reach the ground is 0.9 s

Step-by-step explanation:

Given;

height of the apple tree, h = 4 m

acceleration due to gravity, g = 9.8 m/s²

The time taken for the apple to reach the ground is given by;

`h = (1)/(2)gt^2\\\\t^2 = (2h)/(g)\\\\t = \sqrt{(2h)/(g)}\\\\t = \sqrt{(2*4)/(9.8)}\\\\t = 0.9 \ s`

Therefore, the time taken for the apple to reach the ground is 0.9 s
