Given two vectors A =  -3 i + 4 j   and B = 4 i – 3 j  . Let  C = A x B . Which direction does C point to?

You throw a ball vertically upward from the roof of a building.  The ball leaves your hand at even with the roof railing with an upward speed of m/s; the ball is then in free fall. On the way back down, it just misses the railing and hits the ground s after it leavs your hand.  How tall is the building?
