They are a great way to beat the summer heat, with much milder temperatures at higher elevations bc there is fresh air, and studies have shown that living in higher elevations can have positive health benefits, such as improved cardiovascular health, weight loss, and longevity of life.
        
             
        
        
        
Answer:
Point 3 for kinetic, points 1 and 5 for potential 
Explanation:
There is one point that the ball has the most kinetic energy it is at point 3. Point 3 has the most kinetic energy because it has gained the most speed since it was dropped and it also is right before it starts slowing down from trying to go up again. Points 1 and 5 have the most potential energy. When the ball is at point 1 or 5 it is at its maximum height thus it cannot swing any further, so it stops for a split second and gains a large amount of potential energy before it is released into kinetic energy when it falls back down.
