Dave runs off of his diving board in panglao, Philippines with a horizontal velocity of 8m/s. He hits the water in 3 seconds. His motion is show in the dot diagram what is the horizontal velocity of Dave 2 seconds after he leaves the diving board?

wavelength divides in half and speed stays the same.

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
