For each release height, a gate was located at half the release height. explain why the bob does not appear to have half of its maximum speed at this point.

= √2

Explanation:

Let's use the law of conservation of energy, to find the speed at medium height

Starting point Higher

             Em₀ = U = m g y

Final point. Lower

              = K = 1/2 m v²

             Em₀ =  

             mg y = ½ m v²

             v = √ 2g y

For the average height y = h / 2

           v = √ 2 g h / 2 = (√ 2gh) √ ½

Let's divide the two relationships

          v / v_media = √ mgh / (√ mgh / √2)

          v / v_medio = √2

From here we see that the speed is lower

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
