Answer: 1. the object is moving away from the origin
4. the object started at 2 meters
5. the object is traveling at a constant velocity
Explanation:
<h3><u>Answer;</u></h3>
Argon
<h3><u>Explanation;</u></h3>
- Phosphorus is an element found in group 15 of the periodic table, it is one of the element that belongs to nitrogen family.
- The element phosphorus exhibits allotrophy, namely; white phosphorus, red phosphorus and black phosphorus.
- <u>Phosphorus, particularly the white phosphorus combines with oxygen so easily that it catches fire automatically. Thus, as a safety precaution, white phosphorus is stored under water in laboratories.
</u>
- <u>It may be also stored in argon, since argon is an inert element which belongs to the noble gases group.</u>
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
