To solve this problem we will apply the concepts related to the kinematic equations of linear motion. We will calculate the initial velocity of the object, and from it, we will calculate the final position. With the considerations made in the statement we will obtain the total height. Initial velocity of the acorn,

Also, it is given that the acorn takes 0.201s to pass the length of the meter stick.

Replacing,


The height of the acorn above the meter stick can be calculated as,




Also the top of the meter stick is 1.87m above the ground hence the height of the acorn above the ground is


Answer:
5seconds
Explanation:
because she was going through the same time
A 4x100 relay is where 4 people run 100 meters and a 4x400 relay is where 4 people run 400 meters
