No additional force is required because it's already going downhill
Answer:
b.it depends on the distance it falls
True
The sample of the experiment is randomized in randomization.
1) Balanced
2) Not balanced
3) Not balanced
4) Balanced
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
