Answer:
The answer to your question is below
Explanation:
To explain what happens with the ball we must remember the Law of Conservation of Energy.
This law states that the energy can be neither created nor destroyed only converted from one form of energy to another.
Then,
At the top of the hill, the potential energy is maximum and the kinetic energy equals to zero.
When the ball starts to roll down the potential energy will be lower and the kinetic energy will have a low value.
At the middle of the hill, both energies have the same values.
At the end of the hill, the potential energy will be equal to zero and the kinetic energy will be maximum.
Answer: 54.55 m/s
Explanation:
Distance = 300 m
Time = 5.5 s
Average Speed = Total Distance/Total Time
= 300/5.5
= <u>54.55 m/s</u>
Hope this helped..
The correct answer is refraction.
