rock x is released from rest at the top of a cliff that is on earth. a short time later, rock y is released from rest from the same location as rock x. both rocks fall for several seconds before landing on the ground directly below the cliff. frictional forces are considered to be negligible. which of the following graphs best represents the vertical displacement of rock x as a function of time starting from immediately after the rock is released from rest? take the positive direction to be downward.

Iwas in a argument about a certain class grade with my teacher. it was a ‘a-’when i felt that i deserved a ‘a’. i showed him (my teacher) why i felt i derserved so. i questioned what i got wrong and showed him what i learned. i look back to that teacher with nothing but love and support because that’s the class that i actually learned the most. the moral of the story is to see where the other person is coming from and what they have done. also, when in a conflict, never attack the persons character. this will just make the argument end poorly.
