While on an expedition, you and your team stumble upon a seemingly endless pit cave (vertical cave) hidden by dense jungle. You drop a rock down the cave opening and find it takes 9 seconds for it to reach the cave floor. Use g = 32 ft/s for the acceleration of the object due to gravity and assume there is no air resistance. a) What is the speed at which the rock hits the ground? Speed ft/s b) What is the distance from the cave opening to the cave floor? Height ft
