Four rocks are thrown horizontally from a building, with varying speeds and from various floors. Rock 1 lands a distance r away from the building, rock 2 lands 2r away from the building, rock 3 lands at distance 3r, and rock 4 at 4r. Ignore air resistance.

Drag the rocks into place to select the rock that was thrown with the height and speed shown. If there was no rock thrown with a certain combination of values, drag "no rock" into that slot. You will use the "no rock" answer more than once.
