A stone is thrown straight up from the edge of a roof, 700 feet above the ground, at a speed of 10 feet per second. (A). Remembering that the acceleration due to gravity is -32 feet per second squared, how high is the stone 2 seconds later? Don't forget to enter correct units.

(B). At what time does the stone hit the ground?

(C).What is the velocity of the stone when it hits the ground?
