From the question, The kinetic energy of the fired arrow is equal to the work done by the bale of hale in stopping the arrow.
We make use of the following formula
mv²/2 = F'd................... Equation 1
Where
- m = mass of the arrow
- v = velocity of the arrow
- F' = average stopping force acting on the arrow
- d = distance of penetration
Make F' the subject of the equation
F' = mv²/2d.................. Equation 2
From the question,
Given:
- m = 20 g = 0.02 kg
- v = 60 m/s
- d = 40 cm = 0.4 m
Substitute these values into equation 2
Hence, The average stopping force acting on the arrow is 90 N

Separate the barriers so they have a 2cm gap between them.
Sowers has spent her career fighting for gender equality and it passionate about it .
B.) Carbon Dioxide because the carbon is surrounded by oxygen
Light having a dual nature and acting like both a wave and a particle is the correct statement in this scenario.
<h3>What is Light?</h3>
This refers to the electromagnetic radiation found in the electromagnetic spectrum that is perceived by the human eye and has a dual nature. It doesn't require a medium for its propagation unlike sound.
The dual nature of light is as a result of it behaving like a photon which is why it travels in straight lines.
It also behave like a wave because it undergoes processes such as reflection, refraction etc which are common to waves.
