Two stones are thrown vertically upward from the ground, one with three times the initial speed of the other. assume free fall.
part a :

if the faster stone takes 8.00 s to return to the ground, how long will it take the slower
stone to return? t= ?

part b :

if the slower stone reaches a maximum height of h, how high (in terms of h) will the faster stone go?

im sorry i dont know

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.
