For the purpose of the problem we can consider only the motion on the x-axis (horizontal direction).
We have two forces:the horizontal component of the force F of 3320 N acting forward, and the backward force of 550 N.
The horizontal component of the forward force is
So, the net force is
in the forward direction.
Based on the nature of reflection of light from surfaces, smooth surfaces produce regular reflection while rough surfaces produce diffuse reflection.
<h3>What is reflection of light waves?</h3>
Reflection of light waves refers tobtye bouncing back of light waves when they hit a shiny surface.
Depending on the nature of the surface, reflection of light waves can either be regular if diffuse.
Smooth surfaces produce regular reflection while rough surfaces produce diffuse reflection.
Based on the properties of reflection:
- A microscopic view of a sheet of paper shows that the surface is rough, thus it would produce diffuse reflection.
- Rough pages are easier to read from than smooth and glossy surfaces because they produce diffuse reflection while reading off smooth surface causes a glare due to intense regular reflection
- A wet road appears darker because more light passes through and it reflects less light and looks darker
- diffuse reflection do not all pass through the principal focus, thus an image is not formed off a rough surface
Therefore, it can be concluded that the rough surfaces produce diffuse reflection while smooth and glossy surfaces produce regular reflection.
