Yes, it is possible to determine the final speed of the rollercoaster if the initial speed and the height to be reached are known.
According the principle of conservation of energy, the total kinetic energy is equal to the total potential energy.
where;
- <em> is the </em><em>initial velocity</em><em> of the roller coaster</em>
- <em /><em> is the </em><em>final velocity </em><em>of the roller coaster</em>
- <em /><em> is </em><em>maximum height </em><em>reached by the roller coaster</em>
Thus, it is possible to determine the final speed of the rollercoaster if the initial speed and the height to be reached are known.

Answer: (1) The correct answer is A.
(2) The correct answer is D.
Explanation:
(1)
Reflection is the sending back of light from the surface without absorbing it. In the reflection phenomenon, the wave does not continue moving forward.
Diffraction is the bending of the light around the obstacle. In the diffraction phenomenon, the wave travels forward after striking around the obstacle.
Therefore, the correct answer is A.
(2)
Amplitude is the maximum displacement in the medium from the rest position.
The amount of energy is related to the amplitude. Amplitude is related to the amount of energy carried by the wave. Low energy wave is characterized by a low amplitude. High energy wave is characterized by a high amplitude.
Therefore, the correct option is D.
Answer:
Constant speed is your answer.
