Asnowball is launched horizontally from the top of a building at v = 16.9 m/s. if it lands d = 44 meters from the bottom, how high (in m) was the building?

This is what i found on google “lithium and sulfide can react together to form litium sulfide(li2s). when lithium sulfide hydrolyses(breaks down) in air, it releases hydrogen sulfide which is characteristized by a rotten egg odor.” i hope this you for what your looking for
