A stone is thrown straight up from the edge of a roof, 925 feet above the ground, at a speed of 20 feet per second. A. Remembering that the acceleration due to gravity is -32 feet per second squared, how high is the stone 6 seconds later? B. At what time does the stone hit the ground? C. What is the velocity of the stone when it hits the ground?
