The diagram below shows a container filled with water. The three holes in the side of the container are sealed with rubber stoppers. The water exerts a pressure of 3000 Pa on the bottom of the container. The cross-sectional area of the bottom of the container is 0.009 m². a) What is the pressure exerted by the water on the middle rubber stopper, if we assume it is exactly half way down the column of water. Give your answer as a number, units are not required.

b) Describe the energy transfer that takes place when the rubber stopper at the bottom of the container is removed.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.

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.
