Answer:
what's the question exactly because what you said was true but what's the question
Answer:
The reflection and rectilinear propagation of light helps in the formation of shadows and also tells light doesn't penetrate opaque materials.
Use the kinematic equation: Vf=Vi+at
Then plug;
Vi=14 m/s
a=5 m/s²
t=20 s. Therefore;
Vf=14+(5*20)
Vf=114 m/s.
A centimeter cannot measure mass because mass is measured by grams.
Answer: Centimeter
