EXAMPLE: A PERSON STANDING ON THE EDGE OF A HIGH CLIFF THROWS A ROCK STRAIGHT UP WITH AN INITIAL
VELOCITY OF 13.0 M/S. THE ROCK MISSES THE EDGE OF THE CLIFF AS IT FALLS BACK TO EARTH. CALCULATE THE POSITION
AND VELOCITY OF THE ROCK 1.00 S, 2.00 S, AND 3.00 S AFTER IT IS THROWN, NEGLECTING THE EFFECTS OF AIR
RESISTANCE. ALSO CALCULATE THE MAXIMUM HEIGHT OF THE ROCK FROM THE EDGE? WHAT IS THE TIME THAT THE
ROCK REACHES TO MAXIMUM HEIGHT?
