Explanation:
Friction is caused by how rough and object is, and how much the object weighs, as this causes it to drag more.
The process of changing from one phase of matter to another is a physical matter.
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.
Final velocity = 0, thus final kinetic energy is 0
