Assuming it was thrown horizontally, the height
h = 4.9*2.33^2 = 26.60 meters
The vertical speed vy = 9.8*2.33 = 22.83 m/s
The horizontal speed vx is just 17.3/2.33 = 7.42 m/s
The final speed is of course √(vx^2+vy^2) = 24.00 m/s
A rock is thrown from the top of a cliff. It lands 2.33 seconds later 17.3 meters from the base of the cliff.
How far did it drop vertically?
What is the speed of the rock when it lands?
