If you shoot two spheres of identical dimensions horizontally off a cliff at identical speeds. One sphere is made of lead and the other is made of aluminum.  I) Which sphere will hit the ground first a) lead sphere b) aluminum sphere c) they land at the same time d) not enough information to solve Lets say both of these spheres were made of copper but had different speeds, one fast and one slow. (These spheres are also identical) II) Which sphere will hit the ground first a) fast sphere b) slow sphere c) they land at the same time d) not enough information to solve
