Answer:
I. Stopping acceleration = 6 m/s²
II. Stopping distance, S = 75 meters
Explanation:
Given the following data;
Final velocity = 30 m/s
Time = 5 seconds
To find the stopping acceleration;
Mathematically, acceleration is given by the equation;
Substituting into the equation;
Acceleration = 6 m/s²
II. To find the stopping distance, we would use the third equation of motion;
Where;
V represents the final velocity measured in meter per seconds.
U represents the initial velocity measured in meter per seconds.
a represents acceleration measured in meters per seconds square.
Substituting into the equation, we have;
30² = 0² + 2*6*S
900 = 12S
S = 900/12
S = 75 meters
Answer:
The types of reflection are; specular and diffuse. This depends on the fine or smooth nature of the surface where reflection occurs.
A mirror has a smoother surface than that of a yellow vase. So there would be a specular reflection when light strikes a mirror, but a diffuse reflection when it strikes the solid yellow vase.
Explanation:
Reflection is one of the properties of light waves which can be observed when light strikes a smooth plane surface. It is the throwing of light back through its initial path. In reflection, the angle of incidence is equal to the angle of reflection.
There are two types of reflection; specular and diffuse. Specular reflection occurs when light rays are reflected from a fine smooth surface, while diffuse reflection is observed when light rays are reflected in all directions due to the rough nature of the surface. Comparing the surfaces of a mirror and vase, that of a mirror is smoother than that of a vase. So there would be a specular reflection when light strikes a mirror, but a diffuse reflection when it strikes a solid yellow vase.
the answer to this question is B
